I'm only a couple of months out yet find myselft in essentially the same place as you. He is doing all the right things. I believe his remorse is sincere. Yet that little voice is reminding me that he cheated before, he can cheat again. I want to let my guard down, but I'm terrified.
I know I can never go through this pain again. If he was ever to have another affair, it would mean divorce.
I have to trust him and trust myself right now but there are days the "what-ifs" make that hard.
I'm working hard to live for today and not borrow trouble that may never come, join me?
