That was my biggest difficulty when W wanted to come back - how could I trust it? After all the lies and deceit? In a way, I didn't want her to want to come back - then I wouldn't have to decide whether I had it in me to take try and make it work. I already had a new job and a new house and I was a few weeks from moving away for good. I wasn't sure it was worth tossing that aside in order to see whether there was any chance to love and trust her unconditionally again.
All I would suggest is that you first of all decide if you even have any desire. Then if you do, make a short list of things H would have to do to convince you that he was sincere in rebuilding your R, and also a list of things that are definite dealbreakers - then tell him what they are. Make him show you it is real. Words are cheap.
