If you can prove the adultery by clear and convincing evidence (higher standard than what is normally required in divorce cases for other issues) then by statute, she would be barred from spousal support unless she can show it would create "manifest injustice" based upon the respective degrees of fault during the marriage and the relative economic circumstances of the parties (which she would have to prove by that higher clear and convincing standard) See Virginia Code Sec. 20-107.1(B).

IMPORTANT INFORMATION: Addressing your issue does not create an attorney-client relationship and I am not providing legal advice. I encourage you to personally contact an attorney who practices in the area of law in order to provide all relevant information before taking any action.
I agree with everything Attorney Parks said. I would note, additionally, that if she has openly acknowledged any of the affairs, or even better, would acknowledge them in court, then the evidentiary standard would be met and you wouldn't have to worry about providing additional proof of adultery.
