Thank you all soooo very much for the replies. They are very helpful. Before all this stress we had a pretty good relationship. We were also like bestfriends.
Since the blow up he has been a little edgy but he is still being honest. We talked about everything and he said he just wants to be able to have fun and not have to come home and stress all the time. I still have a some issues with him mentioning the cheating. He told me that he was just telling me all the thoughts that were running through his mind. He kind of downplays it but it still concerns me. I know I have been hypersensitive since it happen. Looking for any "signs" that something far more horrible could be going on. I really have to work on this.
Tonight he went with his brother to have a few beers. I stayed home so he can have some space and I can recover from the stressful events!
