He didn’t really care about you or any of the other women on the show

Oh, so the romance that started when he kept making you have sex scenes with him in every episode while he was also your boss and then started having them with others and then hitting on the A list singer because he didn't really care about you or any of the other women on the show he was doing the same thing to, didn't work out. Well, I think everyone assumed that the permanent A list actor and his co-star's relationship would last a lifetime given that set of facts. It didn't.

He has a history with women who have needed mental help

He has a history with women who have needed mental help and drug addiction so it shouldn't be a shock that this former A+ list mostly movie actor, despite supposedly being in a relationship with a dependent co-star, is doing his best to hook up with this A list singer who has shown an interest in the actor.
