Hey man. I've been there, too. jjalsop's advice is great. One point I'd like to emphasize is that, at the time, I didn't understand how someone could do something so shitty to someone who trusted them. People can be cruel. Don't try to rationalize, your thoughts will go around in circles for weeks. Forget about it. Do anything therapeutic you can for yourself. Take some time out from studying and go for a swim, definitely do NOT sit in your room all day. Get some exercise and get those endorphins pumping, make sure you start to get comfortable with yourself again. This relationship did not define you, neither did she. You didn't fail, she did.

The best advice I wish I had gotten was to always hold onto your dignity. You will regret the late-night phone calls, the fifteen times you ask just to talk to her one last time, just to try to get closure. YOU WILL NOT GET CLOSURE. This is not going to make sense until a month or so from now when you finally start becoming objective about it again.

This is a really interesting moment that can truly impact your character. Cherish this opportunity. When a man is broken down, it is the best time of his life, as he is then able to rebuild himself the way he always envisioned. DO IT.

When I was cheated on, I watched this interview of Tom Hardy for the movie Bronson for weeks on youtuberepeater.com. A redditor gave it to me. It'll do you good. http://www.youtube.com/watch?v=RstefCPs3kU

I wish I could give you a hug, buddy. Nobody deserves these feelings. Not even the bitch who did it to you. Remember that. Be the man here, and try to let all those feelings go. They're over, and you have an opportunity to be awesome and show everyone how great you are. Take some time over the next week or two to be weak, it's natural. After, carpe diem.

PM me if you ever want to vent. If you have skype and you feel like yelling or crying or just talking, we can do that too. Bro hug.

Best, Evan (cloud7)
