I've got a thing for a guy I'm acquainted at university, but though I don't know him very well he doesn't seem like the kind of guy I usually fall for, who's someone really nice and sweet and gentle. I quite fancy him, but he's not here next year so I need to figure out quickly whether to go for it or not as I'm only seeing him a couple of times again.
I used to be really nice myself, but over the last year at uni, due to problems with some people I thought were my friends I've become a stronger person and I feel like it's affected the kind of guys I go for. I'd never have fancied a guy like this before. I find him really physically attractive, but personality wise, though he's the kind of person who gets good grades and is very sociable and popular, and can be quite nice and has an interesting personality, he's also pretty mean sometimes (mostly to his guy mates) and I'm not sure if he's a decent person inside or not. A few mutual female friends also say he is a douche and hard to understand.
I've spoken to him a bit and he seems to respect me as we share some hobbies which I'm very good at - sometimes he's very charming too - but he can also be a bit cold and dismissive, or just seem like he's in a bad mood and not want to say hi. He'll stare at me for ages, and then when I look back at him he'll glance away quickly, or not smile back when I smile at him.
Am I jumping on a slippery slope here? Should I just forget about him or try to be friends at most?
