Hi Coach: I'm not where you are - haven't even been, so I don't really have a lot of first-hand experience. But it does seem like what you're feeling is completely normal - how could you not feel hurt and have problems with trust. Building trust seems like it might be one of the hardest parts of all this - since it means you'll have to be vulnerable to someone in a profound way again - despite the pain. Taking it slowly sounds like a good idea - though be cautious about your feelings - since you don't want some of the stuff that your brought to the sitch before to come back up again.
I wish I could say something helpful...
Have you picked up any books on rebuilding a marriage?
