I'm 15 and I had been dating this guy for almost a year. Throughout our relationship nothing bad really happened, minor arguments, but that's normal. I always had thought one of my best friends liked him and he had feelings for her too. So I told another friend and she said it was probably nothing, I'm just being paranoid. Then one day out of the blue he broke up with me. The next day at school my ex and my best friend I had suspicions about were hanging out and I found out that they started dating that next day after we broke up. So I just don't know if I should be friends with her, she really hurt me. This was in April by the way.
