Guy vs. Friend

This is probably for the younger members of glow but I'd like everyone's input.

There's this guy at my school who I think I may like but my friends don't think that he's the best guy for me. He's really nice and is friends with people who I'm friends with but apparently he smokes a vape (e-cigarette) and gets drunk at parties. I've never seen it first hand but my friends say that I shouldn't get involved with him but I think that we get along really well and we have a lot in common. I would probably regret it if I didn't at least try.

What do you guys think???
