I'm sorry, such a gay question, but...do you think he likes me? (sorry its so long!)?

Well, you don't have to be the prettiest, most curviest girl for a guy to like you. I think that maybe "shane" just thinks you are a really great girl and he just clicks with you. But then again, I have a lot of guy friends that cling onto my waist, but i don't think we're into each other like that. Oh my gosh! That's so sweet how he sang a song to you though:)! He's either super friendly, or he likes you. Let's hope it's the second one. Good luck! :))
