Appellant appeals from his conviction by a jury of simple assault, D.C.Code § 22-504 (1989), on the grounds that his Sixth Amendment right to cross-examine and confront a witness was violated, and the trial court erred in denying a motion for severance and admitting “unsubstantiated allegations of his prior violent behavior and other crimes evidence.” We affirm, concluding that any error in admissiоn of the other crimes evidence was harmless, and that appellant’s other contentions are unpersuasive.
I
Appellant and his estranged wife, Mona Parker, the complaining witness, lived together for eleven years until December 17, 1987, when Mrs. Parker moved into the home of her uncle, Chauncy McIntosh. In her testimony she explained that she had separаted from appellant because he had made life difficult as a result of various forms of harassment, including prior physical beatings of her, locking her closet door and bathroom so she could not go to work, preventing her from watching television, and making it uncomfortable for her to remain in the same room with him. Specifically, she testified that on December 17, 1987, all the doors were locked so she could not get her clothes or use the bathroom. She further stated that “[a] lot of this had been happening for a couple of weeks,” explaining that appellant had been put out of the home because of physical abuse. “And ... when he came back, although he would not hit me, ... he would make it vеry difficult for me to live there comfortably,” She gave testimony indicating that she could not bathe when she wanted, that her husband would turn off the television while she was watching, and that he generally made it uncomfortable for her to be in the house with him. She elaborated that appellant had been ordered out of the house after he had beaten her and she hаd filed charges in Maryland.
The assault charge arose from events on *722 January 4, 1988. 1 Mrs. Parker testified that she saw appellant on the morning of January 4, 1988, as she and her children were walking to her car in front of her uncle’s house. Appellant, accompanied by an unidentified man, drove up and leaped from his car and began pounding on the window and hood of Mrs. Parker’s ear. Mrs. Parker drove to the police stаtion and filed a complaint at the Citizen’s Complaint Center. Upon leaving the Complaint Center, appellant confronted Mrs. Parker, and after she attempted to push appellant away, he slapped her across the face. Appellant grabbed her by the hair when she attempted to retaliate, threw her to the ground, and kicked her twice before bystanders interrupted the beating. As a result, Mrs. Parker’s face was red below her left eye, her knee was bruised, and her pants were torn at the knee.
On cross-examination, in explaining why she left home in May 1987, for several months, Mrs. Parker testified that appellant had tried to strangle her, so that she could hardly breathe. Further, that appellant, instead оf sitting down and talking to her when he got angry, tended to act violently toward her to show her who was the boss.
Appellant testified that on January 4, 1988, he drove to the McIntosh residence, and as he was walking around the front of Mrs. Parker’s car, she accelerated the speed of her car and caused him to be pushed against the hood of his car. Appellant got back into his car and followed her to the police station and was told to go to the Citizen’s Complaint Center. Later that afternoon when he saw her leaving the Citizen’s Complaint Center and he tried to talk to her, she threw a bottle at him and attacked him with her arms and feet. Appellant testified that he filed a complaint with the Complaint Center and rеceived medical attention for his injuries. Lawyer Thompson, who was riding with appellant on January 4, 1988, corroborated appellant’s testimony.
In rebuttal, Officer Meehan testified that after the January 4, 1988, incident, he noticed bruises about Mrs. Parker’s left eye and cuts on her knee.

Appellant contends that his Sixth Amendment right to cross-examine was violated when the triаl judge refused to let counsel inquire about Mrs. Parker’s prejudice, bias, and partiality in order to show that she had compelling reasons to fabricate a case against appellant.
Central to the accused’s Sixth Amendment right to confront witnesses against him is the opportunity to cross-examine the government’s witnesses.
Davis v. Alaska,
At trial appellant’s counsel attempted to elicit testimony that Mrs. Parker was romantically involved with other men, had filed lawsuits against appellant and reported his threatening behavior to the police, *723 harassed the son of appellant’s brother, did not properly care for her children, and kept a diary of the events of the fall of 1987. The trial judge permitted appellant to cross-examine to some degree about her alleged involvement with other men, the pressing of criminal charges against appellant, and why she left home, and the alleged reporting of appellant’s threats to the police. Further, the judge provided appellant’s counsel with the opportunity to proffer the questions that she wanted to ask and ruled, on a question-by-question basis, whether further exploration into details would be permitted. Counsel also probed Mrs. Parker’s bias both before and after the cross-examination was restricted on a question-by-question basis. When the judge limited the scope of cross-examination he did so on the ground that it was going beyond reasonable inquiry into Mrs. Parker’s bias and was becoming the trial of a domestic relations conflict.
When, as here, questioning seeking to show bias is objected to as being irrelevant or nonprobative, “the party posing the questions must proffer to the court ‘some facts which support a genuine belief’ that the witness is biased in the manner asserted,”
Jones v. United States,
In any event, a review of the record indicates that any error was harmless,
Delaware v. Van Arsdall,
Ill
Appellant also contends that the trial judge erred in denying his motion to sever and admitting evidence in the government’s case-in-chief of unsubstantiated allegations of his prior violent behavior and other crimes evidence. As set forth in his brief, however, apрellant’s focus is on the admission of evidence of his behavior prior to December 30, 1987, the date on which he was charged with threatening to do bodily harm to Mrs. Parker’s uncle. 3
*724
Evidence of a defendant’s other criminal activity is inadmissible except for certain limited purposes.
Tabron v. United States,
In denying appellant’s motion to sever, which included a motion to suppress evidence of other alleged acts of violence against Mrs. Parker, the trial judge ruled that the evidence of appellant’s alleged pri- or violent behavior and other crimes against Mrs. Parker prior to the date of the assault was admissible under exceptions to Drew. 5 On appeal the government makes no argument for admissibility under any Drew exception or analogy thereto, but instead relies on Toliver and its “progeny,” 6 arguing that the evidence of appellant’s prior behavior toward his wife was properly admitted to establish the factual background and context of the charged offenses. The government maintains that the evidence explained why Mrs. Parker was living at her uncle’s home when the threat and assault occurred, helped to portray the level of tension and frustration which generated the charged conduct, and made comprehensible the actions of Mrs. Parker, her uncle аnd appellant.
This court has not read
Toliver
and its “progeny” as broadly as the government. Indeed to do so would come close to eviscerating
Drew.
Rather these cases support the uncritical admission of bad acts and other crimes evidence that is so intertwined with the charged conduct that the latter is unclear without the former, but only where there is a close tempоral relationship. Thus, in
Toliver,
the other crimes involved sales of drugs immediately before the defendant’s arrest.
The challenged testimony regarding appellant’s prior physical abuse of Mrs. Parker was not always specific in time and when it was it did not reflect “events so closely related to the charged offenses in time and place” that they placed the charged offenses “in the context of nearby and nearly contemporaneous happenings.”

at 17-18 (quoting
Williams v. United States,
Although the government introduced rebuttal evidence to corroborate the existence of Mrs. Parker’s injuries, the defense offеred testimony to corroborate appellant's version of what had happened on January 4, 1988. In this sense the government’s case was strong but not overwhelming. On the other hand, appellant’s efforts to show Mrs. Parker’s bias led to the introduction of other evidence of appellant’s tendency toward violence. The trial judge tried to avoid having the triаl turn into a domestic relations proceeding, but appellant’s defense strategy involved examina
*726
tion in considerable detail of the relationship of the parties.
See
Part II,
supra.
Consequently, appellant is hardly in a position to complain of prejudice. Further, appellant’s acquittal of the threats charge demonstrates the jury was able to weigh thе evidence carefully, notwithstanding the evidence of appellant’s prior conduct.
Cf. Winestock v. United States,
Accordingly, any error was harmless and the judgment is affirmed.
Notes
. Appellant was acquitted of threats to do bodily harm. D.C.Code § 22-507 (1989).
. Appellant’s reliance on
Villaroman v. United States,
. Appellant was acquitted of this threats charge. Appellant filed a motion to sever in the trial court seeking to sever the assault and threats charges, disputing the government’s position that the offenses were of the same or similar character or based on the same act or a common scheme or plan, Super.Ct.Crim.R. 8(a). Further, he argued that he would be "unduly prejudiced” since the jurors might infer criminal disposition upon hearing evidence of two distinct crimes, citing
Drew v. United States,
The government also notified appellant in its opposition that it intended, in its case-in-chief, to bring out that the assault and threats were part of "аn ongoing criminal transaction which began in October 1987,” prior to which Mrs. Parker sustained a number of assaults, and when beaten in October, 1987, she decided to report the incident to the authorities. Also that subsequent beatings in November resulted in appellant being ordered to stay away from Mrs. Parker for 30 days and a civil protection order issued in Maryland. In the government’s view, appellant’s motive and criminal intent were relevant issues; because his actions were part of a common scheme or plan, the evidence of both incidents was necessary to prove appellant’s mo *724 tive and intent behind his threats and assault. Accordingly, it viewed the evidence admissible under several of the Drew exceptions.
. For example, in
Green v. United States,
. The trial judge appeared to accept the government’s argument that the evidence was admissible to show intent, motive, lack of accident or mistake, common scheme or plan, as well as to show surrounding circumstances. He characterized this as a domestic relations case in which everything would come out.
.E.g., Green, supra,
. The government has essentially abandoned the
Drew
analysis that it propounded in the trial court,
see
note 3,
supra,
and we agree that its view of the common scheme or plan exception under
Drew
is flawed. As the court stated in
Ali, supra,
The distinguishing characteristic of the common scheme or plan exception to inadmissibility is the existence of a true plan in the defendant’s mind which includes the charged and uncharged crimes as stages in the plan’s execution: the series of crimes must be mutually deрendent. See also 2 Wigmor, Evidence § 315 (Chadbourn rev. 1979). Since the government does not argue on appeal that the evidence was admissible other than under Toliver, we do not address whether it would be otherwise admissible.
