I think he loves the buzz she gives him - not her....and in time that fades and the WAS realises that reality just doesn't add up the way they thought it would.
Calm down and get to work working on you.
My H had an A for 18 months. He was right at the bottom of my list and got fed up with that. He though I no longer loved him. In a way I was lucky that I did not know the A was going on....so when I started putting him higher on my list again he new it was because I had changed within myself and not just as a reaction to finding out he was having an A. It made him come clean about the A and recommit to me. Even so - he still felt obligated to letting OW down gently - the b!tch that tried to ruin my M!! Now, (look at my time line), he sees the OW for what she was. Give it time.
