crush on flatmate

yeh she's at the same uni and she's lives like a 5 minute walk away. plus, she's really nice so I don't think I could ever screw her over. I just don't know if I should flirt back or not in the hope that if he realises he like me he might break up with her at some point?

Well, basically, I started uni about a month ago and I have a MAJOR crush on one of my flatmates. The problem is, he has a girlfriend and they have been going out for over 2 years. Usually, I would just back off in this kind of situation, but the problem is that I think he is flirting A LOT with me, even the other girls on my flat have said that they think he likes me. Whenever we go out and he has a few drinks then he is all over me. He always puts his arms around me and kisses me on the cheek a lot. Then he holds my hands and pulls me close to him and just stares into my eyes and smiles for like a minute. Also, everywhere I go, he follows and I always catch him watching me when he's talking to other people. Maybe I'm just seeing what I want to see, but I'm pretty sure this is serious flirting. What do all you guys out there think? I'm also really confused coz he only does this after a few drinks. During the day we just joke around and act like really good mates. But he doesn't do this with any of the other girls in the flat. I don't know what to do. Should I speak to him or should I just leave it and push him away etc when he does this? But I don't want to lose him as a mate coz we get on so well but I'd love to take it further if he wants to! What do u guys think?

You're not called Jenny any chance?

Push him away. If he has a girlfriend he's a no go zone.

I'm not called Jenny by the way. How did u come to that conclusion? Thanks everyone for your advice. I'll just back off then and hope he stops doing it and that I find someone else who isn't taken!
