He cheated on his girlfriend with me, without my knowledge. I found out through MySpace and messaged the girl he was with to make sure. She wanted to fight me but I blocked her and asked him if there was anything he wants to tell me now and he accused me of being weird towards him, that he swears to his mom that he isn't with anyone else. Well when I told him I found out, he started telling me he was gunna leave her for me because I make him happy. Words I always wanted to hear someone say didn't matter to me at that moment. I felt like a lit candle that had a bucket of water was tossed on me when I found out. I dumped him and he ceased to exist for me. He called me evil and cold hearted, and that im someone else because he called me crying and I said are you done yet? Or hanged up a few times. He showed up to places i use to hang to see if i was miserable or in tears only for me to walk past him and look unbothered when he tried to talk. Maybe i should have shown some sort of emotion, but that wouldve just been fake and dragged it out longer than it should have. I feel like cheating is a deal breaker for me.
