benwa,

I know what you are going through. I still feel the pain. I had a few of these weekends where W went w/Om to have fun and I was at home w/the kids. Don't give her anything. Don't give her a card. 'Act as if' everything is ok and TAKE CARE OF THE KIDS. Can you go to somebody? Friends w/children. Get out of the house? That was the only thing that helped me through those weekends. Fortunately I had friends, 2 couples w/kids. I don't know where I would be w/o them.

Hang in there,
