Annie, thanks for sharing too, my regret is that when I and my best friend were 19, I slept with her fiance, it was totally out of character for me, I was a virgin at the time, and he turned up at my house the night before the wedding, drunk, saying he didn't love my friend, I feel so ashamed about that. she never found out, but every opportunity he had, he'd try to see me. I eventually moved to another city, and my friend couldn't understand why I left, that was 30 years ago now. If she ever bumps into any of my family, she still asks after me. It eats away at me every day. I've heard that they divorced because of his infidelity about 10 years ago. I would never contact my friend to tell her what happened, I don't think it would do anything except cause pain, so I will keep that secret.
