<human>: I've liked my friend "Ashley" since we were in high school.  We were both kind of geeky, and we had the same hobbies.  We've been part of the same group.  In college she lost around 40 lbs, going from 150 to 110, and she became gorgeous, which only made me more attracted to her.

I really thought she liked me too.  She's never dated anyone, and I probably misinterpreted us being best friends as something more.  Nothing physical ever really happened between us or anything else that would point to her wanting to try us being together.

I broke up with my ex-girlfriend a month ago (honestly because I still wanted to be with Ashley) and asked her out three weeks ago.  She told me that she still saw me as a friend and that she wasn't really ready to be in a relationship.  I was embarrassed, but I told her it was fine and that I got it.  It didn't make me want her any less, but it honestly felt good to say.

Two days ago I learned that she started dating "David," a high school kid, and I've felt like shit ever since.  He's her younger brother's friend, and they hit it off.

I can't stop thinking about it.  David is everything we weren't in high school, he's popular, on most of the sports teams, and I just feel worthless compared to him.  I've met him a couple of times, and while he seems nice, he still represents what we (Ashley and I) didn't really have (a great high school experience) and it makes me feel like those kids that did still win.  I kind of hope this is some weird complex or something on Ashley's part, but I don't know.  

How do I stop comparing myself to this kid, and how do I make it hurt a little less?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Got rejected, she's started dating a "jock" high school kid.  How do I feel better about this?
