Yeah, I don't understand why he would stay with someone like that and given how long they've been together, can't even make the argument that's it's the best for the kids. Sounds like it was terrible before they were even born.

Does he worry about the children if they broke up, as in on the off chance custody became an issue? Courts typically sides with mothers or not, unless your son has a checkered past as well, I'd like to think they'd give full custody to him.
