Is his ex prettier than me?

I have had major issues letting go of this subject. We have been together for two years and it shouldn't bother me but it does. His ex seriously is gorgeous, I don't see anything wrong with her at all. But I see everything wrong with myself. All my boyfriends friends talk about how I'm gorgeous and WAY better than her in every way. And my boyfriend told me "Yeah she is pretty, I don't date ugly people. But prettier than you? No. You have things that she will never get close to coming to. You're gorgeous in every way, physically and your personality." But she is super skinny and has blonde hair and is gorgeous, and I'm skinny but I have this hourglass figure, so my curves make me feel insecure. I guess all I am wondering is how to accept his answer and believe him. I hate feeling like his ex is better than me. It's a stupid insecurity.
