Hey KDU...just a few words of encouragement here. It sounds really good for you, and I know you don't want to get your hopes too high. But let yourself believe it, just a bit. Your H seems to be doing everything he can to be transparent, to let you know every contact with OW, and to show you everthing he can so you don't have to wonder.
That said, neither you nor he can control how OW will behave, and right now she is going to try everything in her power to stop your reconciliation. Don't let her do it! IF your relationship fails, let it be solely on you and H. Don't let it fail because she gets to you and you start reacting to her bullsh!t. Not that I think you will fail...but you get my point here - it's very hard I know but if she sees she can't get to your H, she will next try to get you to leave him, and then she can move in and pick up the pieces. (I know I made OW happy when I left town. Life lesson - NEVER do anything that will make an OW happy! )
Hang in there, this may be a tough time, but don't forget your goal!
