I'm sorry you're feeling blue again. I don't think your H would intentionally lead you to believe that the two of you would get back together just to dump you when you move back. Your H wants to be with you but is very weak right now and OW happens to be there for him. She's not the one he wants to be with but he's addicted to the fantasy. This reminds me a lot of my H. You're only a few days away from moving back with H. You have to prepare yourself because it won't be easy to go through H's withdrawal from OW but it doesn't have to be over for you. Take a look at my thread. I just posted some interesting stats about A's.
