The last conversation you had with your H was bad, but please remember not to base your current emotions on that. He was angry, he lashed out -- he was doing it on purpose, to push you away. That's fine, be pushed away. But don't think that anything he says is true right now. Does he love the OW? I doubt it. Will they get married? We'll see. Does he hate you? Highly unlikely. My H said all kinds of nasty things to me about how he hated me, was disgusted by me, thought I was a terrible wife...and he recanted all of that eventually. Try to remember that he's going through something, too.
It sounds like counseling would be good for you, regardless of what happens with you and your H.
