My Hot Best Friend

I'm a 5'2 virgin guy who happens to be kind of fat and ugly,my best friend, in the other hand,she is a smoking hot 5'7 blonde with big blue eyes and the most incredible tits I ever seen ,she knows I lust for her,but she doesn't care that much, I assume is because she felt ugly in highschool and now she likes to be reminded how hot she is, idk,the thing is ,despite saying multiple times that she doesn't want to sleep with me ,she has been sharing her sexual stories with me ,she have sent me nudes , sometimes I felt like I pushed to hard asking some stuff. Am I a terrible friend for this or is completely her choice? do I have a chance with her in the future?
