I remember when my WW moved out. Leading up to it I thought to myself I should help. I probably should pay off her car, buy her a new bedroom set etc. These were my initial, quick reaction thoughts. Why those came into my head, I have no idea, probably because I cared so much about her. But even before I came to this sight, I thought about it said "WHAT ARE YOU CRAZY?!?" Why would I help facilitate this in anyway? I certainly do not want this. This is a long way of me saying that I would not help in anyway. Let her start dealing with things completely on her own. Taking the kids somewhere when she does it is probably a good idea. Besides that, I don't think there is much advice to give since you are staying, just let things flow.
