So you know enough to criticize me for NOT having told him but not enough to offer suggestions or feedback about possible ways to do what you suggest? What was the point in even responding to me. I feel hurt by your response, although I hope it was intended to be helpful.

It's not that HE or WE can't get over my past, it's that I can't. HE is awesome about it. I am the one with guilt and shame about talking to him about it. Once in awhile when I do feel comfortable talking to him, he is completely supportive. You're right, I do feel some discomfort with being completely open and honest, but this is my first experience in a healthy relationship (not just romantic, but friendship, family, etc) in which communication was encouraged-- I'm not going to be perfectly skilled over night. And I don't have any friends I can talk to about this. I just feel very alone and lost right now, which is why I came here for support. This forum is supposed to be for support, but now I feel even more alone. Sorry if I'm being dramatic.
