LB55 - Just wanted to check in on your thread and say hello. You have no idea how much you helped me last week get through a very intense flashpoint with my W.
You are doing a fantastic job by the way. Just watching your kids, doing your thing, staying out of the friend zone. My W had that same "divorce a narcissist" book (Splitting?). It must be very disarming for her to see you just going about life. At some point the book disappeared from my house, I don't know why. And I don't care.
Maybe your kids will tell her themselves what they want. It is frustrating isn't it? It will play right into the splitting accusations. You just can't win, all you can do is refuse to play like you are doing.
What is your current custody arrangement, and are you planning that to be final for the D? If you want 50/50, I would suggest you fight for that now - otherwise you may have a 2nd expensive and draining court battle later.
