You are doing the right things,make her file if she wants one.She can't sell the house without you saying ok or getting D.Probably what forced me was that X got terrible mean and threatening.So I said fine.Now life is good and she knows where she wants to be and I think if I hold out we will be back together.This is the big reason so many states are making seperation for long period before D mandatory.As for the kids we have always interacted good.But for a long time it was I picked them up on wedesday and wouldn't hear from her until I took them back on sunday.We have joint residesual custody which is the way to go.Start this arrangement while seperated and keep a journal.Good luck
