How I Am Dealing With a Boyfriend Who Cheated

My (ex)boyfriend and I have been dating for 9-10 months. He was off to college a few months ago so we did long distance for a while. I am a very trusting girlfriend so I tried not to let it bother me when he would post other girls or talk about them. The other day I found out he betryed this trust.

Flashback to last week.. I was starting to realize that our relationship was not going to work out: we were just so different and the distance was not helping. He wasn't making me a priority at all and I felt like I didn't even mean anything to him. He recently posted a photo of him drunk with some other girl in her dorm room. So, I called him with the intention of breaking up with him but I was still open-minded to staying with him if he really wanted to. "I love you" "You're so special to me" "I would never even consider dating anyone else here" ...

I was so close to telling him "Okay, we can just try this again one more time.." but something in the back of my mind was forcing me to mention how his picture with the girl made me feel. So I told him how upset it made me. Stupidly, I also said "I know you would never do anything with her but if you're that drunk you never know what could happen.." I was waiting for a "You know I would never do that to you" but instead, he says.. "I kissed her."

Embarassment. Humiliation. Heartbreak.

It took all of me to not cry on the phone. Instead, I asked calmly if he was going to tell me. He responds "later.." So I say "Okay. We're done." and I hang up and blocked him on everything he could contact me by.

Don't get me wrong I cried hard, for a good 20 minutes (which is not a lot for me). The next day I was as happy as I have ever been.. I have just been focusing on the fact that I finally got rid of a big source of negativity in my life. In some twisted way, I am almost glad he cheated because if he didn't, chances are I wouldn't have dumped him. What is keeping me going is that while I got out of a bad relationship, he is dealing with the guilt and suffering through what he did to himself. For the next few weeks, whenever someone asks him how I am, he gets to tell them that he is an unloyal liar and stand in front of them in shame.

The only thing that scares me out of this is being able to trust anyone ever again... Every cheater has at some point said they would not cheat.. Has anyone ever dealt with something like this and was able to overcome it?

Also, he is coming back in December for his winter break and I am terrified of seeing him in person, because I do not want to risk giving in to whatever lie he can feed me next.. Advice?
