What does it mean when a guy says you're very nice?

Well judging by the way you asked the question, my guess would be you kinda have a thing for this guy. lol When someone says something like that it can be his way of flirting, or being nice. If im correct in saying you like him, don't give up on it. Get to know him and who knows....maybe you guys can end up in a relationship oneday. Either that or im completely off and yo just wondered what he meant lol. Either way, I hope i answered your question.
