Wow! I don't think I would have the strength to do this either. Something is up with him, my friend. I don't see him going through all of this unless he was contemplating something. Unless he was contemplating YOU...
I'm not so sure i would be worried about OW at this point. I would agree that he is trying to recapture something.
Angel, please forgive me for not knowing more about your situation, but are you in a place where you can ask your H a few questions about this?
I agree, this is just strange and you might just well get your wish.
I am praying for you and your reconciliation. I'm praying for your peace and I'm praying for some answers for you.
