I'm with my girlfriend for over two years now. We've had our share of quarrels, but, overall, we get along quite well. However, recently one of her friends has started to catch my eye. I don't know how or why, but it simply happened. The problem is that the other girl is not some insanely hot chick that you would simply like to fuck the very second you first see her. I thought nothing special of her the first time I saw her, but after having a few short conversations with her I had to admit to myself that she really appeals to me. If I weren't already in a relationship, I would definitely ask her out and try to have something with her. But, being in a relationship, I feel awful about the whole thing. I really like my girlfriend and I have never cheated on her, nor would I do so now. What the hell am I supposed to do now?
