(summary stolen from another site) Woman (Quinn) makes a flash based game (more of one of those text based choose your own adventure things) about battling depression [really good game, I might add]. The game receives critical acclaim from gaming journalist websites, and makes its way onto Steam. Quinn's ex boyfriend releases chat logs about her cheating on him with various men. Some of these men are key players in gaming journalism, and are responsible for the positive press Quinn's game received.

Article brings up an interesting point --
"This is a woman who said she had principles about sex - that someone cheating on someone else means the sex with their actual partner IS NOT CONSENSUAL."
Which when I think about it makes sense and is a point I agree with. I don't think it's overblown, either. I think when someone agrees to only sleep with you and violates that agreement in secret, and continues to have sex with you, it's non consensual.
Further playing around with semantics --
"Marital rape, also known as spousal rape, is non-consensual sex in which the perpetrator is the victim's spouse. As such, it is a form of partner rape, of domestic violence, and of sexual abuse." (Wikipedia)
These may not work as legal definitions, but I don't think they're a big stretch from the truth.
