Ok, so i liked this guy who happened to be one of my close friends, in a group of seven. Apparently he liked me too, but we needed a little encouragement from our other friends before anything would happen. I had put off making a move because i found out that one of my girlfriends had a thing for the same guy, so naturally i wouldn't want to hurt her by going out with him. She and I talked about him a bit and she said that she didn't like him any more. I didn't believe her, but then she would go and try to convince him to ask me out. When he finally did, my girlfriend started to pull away from me. We don't talk like we used to and we can go days without talking at all. She is really weird and i have confronted her about the weirdness and she says nothing is wrong. Should i break up with my boyfriend for the sake of my what was once a strong friendship?
