my ex husband sniffs around too, even tho he has a new gf and that looks pretty solid, at least from my POV. I think it's about control. He doesn't want to get back with me, but he wants my attention and to be important to me. Both of these things are really annoying, but there isn't much to do about it other than the boundary stuff people have already posted about. Some men feel entitled to this kind of thing.

I love all these people replying telling you what to do when they have no damn clue what the divorce agreement was between you and your ex-husband.
