Dave-- I have been MIA again, and sad to see your D having such a hard time. As a mom, I can't imagine moving away from my kids...I can hardly believe that my H did it. It shows the pain and confusion he is suffering from, I suppose.
If you are not comfortable with W coming and going on a whim, you really should say something to her. Is it authentic to hold in resentment about your space? She left--why is she making the rules about when to be in your house? I don't know...just seems like it may keep her stuck for a while, since she feels comfortable doing whatever she wants without regards to your feelings, and you will let her do it.
I am glad that you are trying to hang in there, if only for the kids. It can be so frustrating to deal with these aliens, and it is understandable to get frustrated and wonder what the point is sometimes.
