About a month ago, I slept with my ex right after he told me he was engaged. I had no idea why I did and I refuse to blame it on the insane amounts of alcohol we drank like he does. He still calls but I know its just for sex, so I told him I couldn't be his friend anymore. I realized that I want more than what he can give me. If that's the case for you, what are you expecting to get out of it?

That's horrible. How would you feel if you cared for someone and found out they were cheating on you? Grow up, and Mr. "CrazyFly" have some self control. Jeeze.

He has a girlfriend... leave him alone! Knowing he has a girlfriend (for 3 years) what you did was wrong! Don't ask him anything and just move on.

This is not a question of right or wrong. When people are horny, all logic and reason goes out the door. You do what you have to do to get sexually satisfied, and make best of the sexual times.. go enjoy and have a banging good time!
