I'm very attracted to a guy at work, but he has a girlfriend of 5 months. While she was on vacation last week, we hung out everyday, and ended up hooking up. I don't regret it, and she heard rumors of us being close, but I don't like being number 2. He says he likes me, but just doesn't want to risk it all without knowing what he's getting himself into. I can be a quite a flirt, and I've calmed down just to show him there's more to me than my looks. He thinks that just because I'm hot, I might not be faithful. My mother told me to keep an open mind, and a friendship and to ignore the comments people make. But some people say to ignore him completely.
