So sorry you are here. You've come to the right place for help, understanding, or just to vent. Most of us here have heard the "I love you but not in love with you line". I heard it prior to finding out about Hs first 2 year affair. The sitch is confusing to you because your H is confused and conflicted. Not sure they want to give up the good things in the marriage, but wanting "more excitement" or whatever.
Could you share a bit about yourselves. Ages, kids, and their ages? It looks like you've been married 11 years?
Take all the advice in Job's post, especially GAL. It helps a lot. If I was in your sitch, I would not want to have sex with H knowing he is open to a relationship with someone else. That's way to much cake-eating for my taste.
