we have been talking for months and he never mentioned girlfriend when I told him he was cute and that we should go out sometime... I have feelings for him too...

Why would he tell you he doesn't hate you for sleeping together? Why should he hate you... sex takes two people, if he consented and you consented, why would he have reason to hate you?
It seems more reasonable that you should be the one that hates him, if he slept with you while he had a girlfriend, and didn't tell you about it. Now it just means that he sees you as a side girl that he doesn't have to be honest with. Though he is clearly not honest with his girlfriend either, so dishonesty seems to be a character trait.
To be honest, it shouldn't be the case of 'never contact me again until you are single'. It should be 'never contact me again. Period.' If he cheated on someone with you, he will have no problems cheating on you with someone else. So if you are not down with open relationships, this seems like someone you should really be having nothing to do with.

You should never talk to him again. He's a jerk who used you for sex. In the future, avoid this by being harder to get in bed and not just sleeping with a guy so quick because he's cute and pays you some attention
