I want to break up with my girlfriend. We have the best relationship that I’ve ever seen. All my friends tell me she’s a keeper and that I’m stupid to even think of breaking up with her, but all I can think about is other girls. I feel so selfish wanting to ruin something so good just so I can have sex with someone else. I love her, and don’t want to hurt her. I almost cry everytime I see her because I know I’m going to have to break her heart. I’m such an idiot.
