My friend's girlfriend
I'm friends with this couple and I get along with both of them but I typically get along with the girl better, the only problem is I feel a little bit uncomfortable when I'm around her.
We have a bit more in common so I enjoy her company more but I feel uncomfortable because I'm attracted to her. Both physically and mentally I'm attracted to her, she's a beautiful girl with an even greater personality.
And this makes me feel uncomfortable, because she is my friend's girl and while I may not deserve a world's greatest friend mug I'm a firm believer in the rule, you don't hit on your friend's girlfriend.
As far as I can recall I've never consciously hit on her but It wouldn't surprise me if I have done so subconsciously and thinking about it makes me feel like shit.
IS this normal that I feel this way?
