Search Results: he does nothing for me in bed

Sorry this is so long!!

I like this guy that I work with, same company but different areas of work, it is well known across the company that he likes another girl that works with me behind the bar, but she has a boyfriend and he has admitted to me that he no longer wants to be with her or see her but he can't help having fallen for her and if she texts him he starts liking her again, and she does nothing to stop this, she's stringing him along.
Anyway we all went on a staff night out and we were drunk, I was talking to this guy at the bar just he and I and was basically telling him that he's a mug for liking her when she's stringing him along and he agreed and said that he can't help who he's fallen for... The same night she saw us talking and took me into the toilets and told me never to talk to him again because he and her are in a situation that although she has a boyfriend she wants to be with him etc. I ended up staying that night at the guys house in his bed (strictly PG - no cuddles or anything!!), and she went mental the next day at him...

She recently broke up with her boyfriend, according to some people "to be with him", and now they're starting to see each other more (more than they already were before!) and are apparently bf and gf now!

I tried to snapchat him the other day saying hey, and he opened but didn't reply. Now at work he's being super blunt and not joking around like he normally does with me... And I just get so upset!!

I'm starting to like this guy, and I really want him to see me as a potential date-- what should I do? I don't know how to talk to him without coming across as needy or desperate and people around us know that I like him. Can I ask this guy on a date? I wanted to say something like "It's a shame, I would have liked to get to know you better"

Okay i will try to keep this short. So i knew this guy a month a go at a party and he is in one of my class too. We've been chatting through fb quite often since then although we dont talk much in class and in person. But there was one day like ten days ago he asked me to study with him and after that we ended up in my apartment watching movie and chill. We talked a lot and he shared a lot of his stories with me and i think it was super fun hanging out with him. We chilled until about 3am and he stayed over though i only had one bed. Yes we did ended up sleeping together but nothing happened. And I haven't really heard anything from him afterwards. He used to message me like every day or two but now its just nothing. We still say hi in class and sometimes sit together but we dont talk much. I dont know exactly but one of my friend said he does have interest in me at least and i kinda thought so too or else why would you message someone super often? I'm so confused now. Cuz i thought after that hangout we could at least become more like friends. Apparently he never talked to me like that night we hang, its like it didn't happen at all... And he is talkative when he is around his friends so clearly he didn't treat me like all those his friends. So did he lose interest? Or maybe he is just a super random guy? But i assume everyone has feeling right? How does he act like we just knew each other ytd? please help me i m so confused now and i think i m kinda into him tho i dont know him that well or for that long > <
