Does he like me for me, or my body?

Okay. so this guy named Greyson is in my 3rd hour, gym. One day in the girls locker room, I was changing and Greyson walked in. I was only in my bra and thong (it was the worst day of the world to wear one!) he was just standing and staring until I screamed for him to get out. I ahve a nice body and all because im in shape. but still no excuse! Don't get me wrong, Greyson is MEGA hot! But it was just super awkward. During gym, we were playing dodgeball, and I'm super athletic and all, but i HATE dodeball! So I was just standing in the back, nd Greyson threw a ball lightly at me then just turned away. So after school i was waiting for my friend Akia to come out of the school, when Greyson came up and was like 'Wanna hang out saturday?' And i said yes, not wanting to be rude, and because he is super mega hot. But when is got to saturday at the movies. Greyson kept putting his hand up my shirt and rubbing my leg. So i let him because I kinda liked him. After the movies he took me in back and we made out. So the next day he texted me and said so now were dating wanna send me a naked picture. Or somthing along those lines. I don't though because i thought it was very gross! But at school during gym Greyson would do things likesqueeze my butt and put his hands down my pants when the teacher wasnt looking. Finally one day when we were at his house laying togather in his bed, of course his hands were all over me. I asked him if he liked me for just my body. He denied it, and resumed grabbing and other things. But I'm still now sure, does he like me for me. Or just my body? I feel used ut i'm afraid to break up with Greyson becasue i think I love him. Help!
