don't give up on your friend just yet. she probably just spoke without thinking.

Here's my story: one of my best friends knew my SO and I were friends but didn't know we were actually dating. so we were talking about CDing one day and she says "I wonder what kind of person would be attracted to someone like that."
of course, at the time I was hurt but didn't respond. so the next time we saw each other I told her that I was dating my SO and she was totally cool with it. She is my closest confident now and is super supportive. I am very glad I didn't over react.

what I did was decide to enlighten her on the topic. now she knows what kind of person would be attracted to a CDer.
