<human>: Can you give me the gist of the text in a nutshell?

So me and my girlfriend of one year are back in school and here's my problem. 

My girlfriend from the first moment we met thought that I was extremely attractive and handsome but I've been getting mad at her because she won't stop talking about other guys. Now it's not her saying that she'd hook up with them, but saying how insanely attractive they are straight to my face.

Now I may have decent looks but I don't have a great body. She keeps telling me during a lifeguarding class we have together how amazing some other guy's bodies are and then there's me. 

Please understand, my girlfriend and I always say how personality is more important than looks, and this just frustrates me. I've also been trying very hard getting in shape and so far so good! I've been in a diet for 2 months and I have a daily workout routine. I just don't know how to deal with this situation thats been going on for a week and a half now and its killing me. 

I just want to know how to tell my girlfriend something about this but have no idea how, if anyone could please help comment, thanks!
<bot>: Girlfriend tells me that other guys are very attractive, I'm depressed about not being "extremely attractive" and want my gf to stop, help?
