I don't think there was any cheating, looking at videos of them together, it seem like they just wasn't on the same page. she seems like she wanted to live a certain way, but wasn't in order to keep him happy. That kind of relationship can be miserableCould you blame her?
If dude really cheated after she likely is the reason he even got an acting career than i dont know
Got to be a disloyal a$$hole to be pulling shyt like that
