Do you think he fancies his (female) best friend?

assuming he doesn't fancy her and they are just best friends. She stays at his regularly with out anything sexual just because its easier.He thought you were to drunk to let you make your way home and you slept in the same bed without anything sexual. Sounds pretty similar.. is there anything else hes done to make you think he fancies you.

Maybe he's gay? Seriously he might be as it would seem normal for him to always be in bed with a girl who he's just friends with?

To be fair he might just like the female attention. I've had literally the same thing with a guy at uni for over a year now and it hasn't gone anywhere. I used to think he liked me but later realised he acts exactly the same way with loads of other girls.

At one point I crashed round this guy's after a party (along with a couple others) and we ended up cuddling up on the sofa to sleep, he literally put his arms around me and we linked hands etc so I thought it meant he might like me but then I remembered another time when I'd crashed at his house and I slept in the spare room whilst another girl shared with him so it probably didn't mean anything. I've since noticed he's just very female-friendly and I shouldn't take anything he says/does at more than face value cause I'm just being a woman and reading too much into it. Maybe you're doing the same thing? Especially if you already know he does the same thing with another girl.

Either way if you don't know him that well you might as well say something to him. That way if it doesn't go the way you want it won't really matter cause it won't be damaging some long-term friendship.

This girl, who is his best friend, is the only one he does it with as far as I'm aware. Everyone says he's a really nice guy and I know he is FAR from a player!

letting this girl sleep in his bed several times without having sex with her? he's probably gay

Probably friends with benefits, ask him. Tell him you like him but are a bit creeped out about what him and this girl get up to. Listen to him explain himself and then you can work out whether he's bull****ting or not.

Not really to be honest, it's just the way he kept looking at me. I am pretty certain he found me attractive but whether that means anything I don't know...

He could have easily have ignored me and left me to go home with one of the other girls we were with or not cared at all.

No. The OP has met this guy once. She has absolutely no right to comment on the nature of his relationship with his best friend, nor imply that he must stop because she is jealous. If someone who I had met once before came up to me and told me that I should stop behaving in a certain way with a friend I would tell them where to get off. What this guy and his best friend get up to is nobody's business but theirs, and to be honest I think that telling someone you like them on the second meeting - with the implication that they as a result must break off anything they have with anyone else - is a little bit forward. It's fine to like the look of someone on the first meeting, but obsessing over them like this is not good. OP, put this guy to the back of your mind, go out, have fun, meet new people and then see what happens if and when you go out with them again in the new term.
