It started out with a Facebook message saying hey what are you doing lets hangout. He spent the night and cuddled.. at work he told me he doesn't hate me for sleeping with me but I'm confused his fb says single 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...
He was drunk when I picked him up so I don't know when I said was he seeing anyone that night he said no...
Should I just tell him to never contact me again unless he is actually single?
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
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.
Not everyone posts their status on fb. Kinda lame these days. He wanted in your pants and he achieved his goal. I wouldn't expect too much more out of him. Unless he makes a huge gesture like leaving his girlfriend and telling you that you are the only one for him, you are just a fun time for him.
Did you date him for a while before sleeping with him? You can either move on or haunt him, your choice. If you're angry, get on FB and thank him for a great night out, see if anyone takes notice? If he deletes your posts, it's a guarantee he's playing. Better in that case to move on. Just call it a good time, no sense being bitter about it. Learn and live? It depends a lot on whether you feel he lied to you, or you just assumed things... Usually if something is "funny" that's your correct intuition talking. So it's up to you, make sure his girlfriend finds out or leave it alone..
