Probably b/c he wants it both ways. Or maybe he's angry w/ himself b/c he knows what he is doing is wrong. Who knows, but for now I would just let it go. He's not actually living w/ you right now, right? I would just detach as much as possible and *help* him to realize that he needs to figure out what he wants. Don't buy into the drama of the whole sitch. Take care of you & the kids and try to get on w/ life as best you can and see how he reacts to that. See what he thinks about you just getting on w/ things w/o him. If he wants to act like a 16 year old kid, let him, but just YOU act like the adult.
