Thanks to everyone for responding any advice or different point's of view are always appreciated!!!

I have been happy around him and nice most of the time. There have been a few times when I have trouble keeping things to myself but I think for the most part I have done well. He is definately more curious about where I have been. He has brought up any R talk not me. I have just been telling him I dont want to talk about it and changing the subject but sunday night we did talk a little. I told him I just want for him to be happy (which I do) and stop being so miserable. I think he is having a hard time facing what he has done and forgiving himself BUT he did this so get over it! I certainly dont expect a thing from him right now. I hear the same crap everytime he comes over and see no changes. I am doing my best to move on with my life without him.

H is coming over tomorrow to see our son so I guess we will see how it goes. Thanks again for all the advice it's great
