I'm sure others will have some better advice. She really seems confused and back and forth. She asks you to come over for a meal and then next says she has paperwork. From the short history, I wouldn't believe it until you see it. But you are reacting the correct way. You can't do anything about it. Good for you.
Reading you sitch has helped me too. I need to remember that I can't control anything my W does. If she's with OM, I can't do anything about it. If she's not being a good parent, I can't do anything to change her. You doing well, keep it up.
Keep posting.
