Is this lust or do I like her?

So this girl at school is soooo fine, I think I'm falling for her. We havnt gone out but she likes me and like her but I can't think of anything besides she's a really hot and she's funny that's the only reason I like her, is this enough to date her? We have snuggled hugged held hands everytime we see eachother. All my friends say I'm using her but I really like her... ALOT. Is this cause I like her or is it lust?
