Hi BeingMe. Just reading through your sitch and thought I would comment on a couple things. First of all, lol, don't apologize for whining...better to do it here!!!!! I do it too!!!
Secondly, I can relate a lot to your situation. I think most people in piecing whose spouses had an A have pretty much the same trust issues. It's a very difficult to hand your heart back over to someone who once had it and broke it on you. Fear that it will happen again is always a problem IMHO.
I wish I had some wise words for you, but I am in a similar situation. I just wanted to drop in and say keep fighting the good fight.....you're not alone!!
