Q My ex asked me if the kids could come over for an hour or two and spend some time with his wife on Mother's Day. Is he kidding me? We have been divorced for five years and I hate that they spend time with her. I guess I have to get used to it because the kids seem to really like her -- and I don't foresee them breaking up in the near future. Do you have any ex-etiquette tips to deal with this? I'm jealous beyond belief, but I know I have to get a handle on it. Help!
