Lisa- the best revenge is living well. Remember that. You are focused on them because you are unhappy right now and feel stuck with all the work, heartache, and responsibilities.
Don't ask kids what they do. Don't talk to him about anything but the visitation. Everything else- nope. If you have business make a list of the things that need discussed and try to do it all at once. Do NOT listen when he talks about his R. He is doing this to make you jealous or hurt you. No other reason. So know this and don't bite.
Take care of you. GAL can start with kids activities. Try to fit some exercise or walks in with the kids. That will be nice for all of you. So many things you can do. You CAN do this. Once you put the focus back on you then your path will be clearer. Also, perhaps without an "audience" they will not be so outrageous and hurtful. Mundane is much better than drama. So let them settle in. Nothing like bo and morning breath and all of that to really give a dose of reality.
I just keep thinking that my H used to go on and on how he hated XW cooking, her family, and the sex was not good. Oh and she was naggy. So I am hoping leopards don't change their spots. Also, she was a cheater. Hopefully she never found DB!
Your H OW is obviously a cheater too. You can bet that may come into play. :-) combine that with a young girl who just got her freedom and likes to drink and party. Again, leopards aren't likely to change their spots. Hang in there.
