Mary, I'm really sorry but I just am not going to be able to host Joe. I don't know what is up with me but he really does not respond well to me. I feel badly because the kids get along well, they are fine at your house, they do well in school. I don't know what is wrong with me but I just am having problems managing the playdates.
Maybe we can try again in 3 months.
I like this approach in general, but I would not say "I don't know what's wrong with me." The emphasis is that he's not responding to OP and OP feels it's beyond her to manage the playdates. She doesn't have to take the blame when nobody is to blame.
