Things I forgot to mention - we've been together 13 years, married 10.
We are still living together due to finances not being there for him to move out and be with her. This morning we were talking about it being Mother's Day, and were talking about the daughter we lost (she was premature and died the day she was born) and he went to hug me, and then started kissing me, passionately, which led to sex that he stopped midway because he began thinking of her ("it feels wrong"). There was also a time last night in the kitchen when we were cooking and he gave me a hug and almost kissed me.
There is obviously a lot of confusion.
