Hey Heather. Have you tried counseling? I didn't see it in your thread anywhere. I know people can move beyond an affair if they both really want it. A counselor was a big help for me alone and with my H. Sometimes just bouncing ideas off of a good counselor is a tremendous help. My C even had days that she was at a free clinic for some of her patients who could not afford, or didn't have insurance to cover. It would be worth the try, if even just for yourself.
Each experience in life has formed me, become part of me, made me stronger.
