One more day!!! So far everything is great. He is civilized with her and has yet to say anything bad about her. What he does specify is how different they both are now and the only thing that they really have in common is the love for their son. He is having issues with her parenting but now he is worried about what he can say and cant say b/c he doesnt want her to try to file for full custody.

Thanks to everyone that has given opinions and advice. We are going to talk when she leaves. We already established that. I am glad that it was him and not me that brought it up though. He did mention that he was a little uneasy about me being "ok" with everything. I told him that I wasnt ok and, explained that I just didnt want to be something else to worry about. So yeah...We are good. So far at least. I dont think I will rest easy until she leaves completely...
