Find someone for you who is not embarrassed. Women are still belittled so much by the world, we have to try to stand up for ourselves. Guys like that make it impossible

The roommate may not be a guy. It could be his other girlfriend.

Maybe him and his roommate got something going on and he doesn't want him to find out! ;) hey you never know

What the hell?!?

Are you his obsessive stalker who thinks you're dating him and he got desperate? That would explain things...

Honey ur not his gf if that's the case

What a ******. I hope you dumped his ass (: No guy should be ashamed that his girlfriend spent the night with him. If anything, he should be BRAGGING about it.

Uh, OP, you need to dump that guy ASAP. If it was his parents he didn't want finding out because he'd get in trouble for having someone stay the night - fair enough, but if he's too ashamed to let his *room mate* know, he obviously doesn't care enough about you to be worth your time.

YDI for not saying ex-boyfriend. Get a boyfriend who cares about you, instead of dating a jerk.

... His "room-mate". Suuurrree. No JK. Seriously though, I woulda told him to buzz off. Don't let people walk all over you. Because once they start, it's hard to stop. (first hand experience$
