Cheating boyfriend

[MTSUGURL]

So, I started seeing this guy in September, but for purely shallow reasons I wouldn't make it official when he asked. He kept trying, calling me, emailing me, and being really sweet when he knew I'd been sick or had had a bad day, and I finally gave in and said "I'm being an idiot. I don't want to be alone, and there's this great guy who is super intelligent, sweet, and really really likes me and wants to be with me. I need to get over the fact that he's not the most gorgeous guy in the world and has an extremely annoying laugh and give him a chance." I figured it was about time I proved that I believe what I say about looks not being the most important thing in a relationship.

I did give him a chance, and things have been going really well until I went to his apt today during my lunch break. (He gave me a key so I can go over whenever I want.) I was going to check my email, and he left on the screen a conversation with another girl saying how much he loves her (stuff he said to me last night). I wasn't snooping - he literally left it right there and he knows I check my email on my break. So I caught him. I ended up talking to her, and they've been together for 6 years. She was really nice, and said that she thought he was cheating, that she was done with him, and she wished me the best. We both broke up with him today. I'm extremely angry. He's been talking about me going to Vermont to meet his family, trying to get me to talk about marriage, etc. I keep putting him off, because I've only known him for a couple of months. Still, what a jerk. That's all I just needed to vent.
