About not being able to stop loving him - I wonder if you just will stop wanting to be with him, this WH who is NOT the man you married. He is someone else right now and might not change.
I'm currently reading this thread, which NM posted somewhere - it's way too religious for me, but the content is valuable. Maybe you'll get something out of it.

Also go back and re-read about Detachment. It might start to make sense sometime soon. Only recently did I start to believe detaching from/letting go of someone/or a situation that was hurting me was the best thing to do..and to stop trying to fix and control the outcome. It's a relief to let go. It's no less sad, however.
