Advice anyone?

Hello to all the lovely ladies on eve. I just was feeling down and needed some advice. This guy I like were in band together. And I mean we text all the time and I always catch him staring at me but it's like he made a comment today about some girls ass and how he loved looking at it and I got really upset by it.. I know I shouldn't be mad but am I wrong? And it made me feel really down on myself because I wasn't blessed with a huge butt.. idk I just feel like i don't fit in. Any words of encouragement would be greatly appreciated
