I hope for your daughter's sake that he doesn't drag her through the mud and pit her against you. That is a very bad man and I've been through it with my ex husband. It is not an easy thing to get through, especially with a teenager! I lost everything in that divorce and for him to do that, he's a POS! That my friend is unforgivable!
I would watch what he buys her in the next few weeks or so. He may be buying her off to stay with him. It doesn't take much to buy a teenager off. I could not compete with my ex and his spending sprees on them. I also had rules. Needless to say, I'm also going to be a very, very young grandmother in a couple weeks!
