Body Image Crisis!!!!!!?

[Mirage]

I moved to Georgia from San Diego California about 2 years ago. I live in a city about 30 minutes north of downtown Atlanta. I'm 19 years old and I still live with my parents who live in a town home in an extremely quiet neighborhood. So as you can imagine, not much happens around me. I met a guy at school who's from Decatur and over the passed year we've started dating pretty heavily. He's been introducing me to his family and all of his childhood friends over the passed few months. Now I'm from the beachy, sunny, bright...San Diego California. Where we eat tacos and surf for fun. But when I met my guy's friends..they were so different. The girls were THICK. With hips and a lot of a s s. They had big boobs..and just crazy curvy bodies. I'm naturally thin and have always been this way. I've always been a little self conscious about my body (as everyone is) but recently it's gotten much worse. Because I had never really met the people my boyfriend surrounds himself with, it didn't bother me so much when he touched my hips or grabbed at my butt. But now that I've seen the REAL Atl...all I can think of is how much SKINNER I am than what he's used to and it doesn't make me feel good about myself. He has never said "I wish you were thicker, or you need to gain more weight" But he drops subtle hints. Like I asked if he would visit Cali with me someday and he answered "Where all the girls have NO BODY? Nah, I'm good." =/ OMG and last night when we were over his friends house..his friends girlfriend introduced herself to me I COULD NOT BELIEVE HOW MUCH BUTT THAT GIRL HAD. Lol..it was so sad. And I was in such a s h i t t y mood. I feel like he wants me to be curvy like all the other girls he's been with. How to I overcome this feeling I have? Does anyone else have a body image crisis?
