How old is your husband, and how old is the baby-sitter? I am going through something similar. I am not handling this very well. My husbnad is sleeping with our youngest daughters X-best friend. When it started I figured out she was only 19, and he was 50.. Brags about how the first time she laid my husband was on his 50th birthday. My daughter was so devistated, she moved out. He was my BEST friend. I will not ever be civil to her, but I don't have to. I wish her parents knew. Take care, and try not to let anger take you over, like I am. I am having a very difficult time trying to come out of it now, and start MY life over.

I agree with callano. Try to be civil, unfortunately you can't control who your x dates. You can control how you handle situations with her. Keep in mind the kids are in the middle when there is friction between everyone. The best thing to do, is try to keep the exchange of the children and a neutral place. Such as: let him drop off at school after his weekend and you pick them up that Monday from school. Minimal contact is the key.

She is not their babysitter anymore, is she? If she is, and you feel uncomfortable about that, change your situation. You can be nice and civil, but remove her from your life as much as possible....
