<human>: Can you provide a brief rundown of the text in within 3 sentences?

19/M here.Freshman at university. I had an unusually weird dream involving a former crush whom I've not spoken to or seen since middle school. After about a week of her constantly popping up in my mind during my daily routines, I decided to look her up on facebook, just to I guess see what the fuss was about or whatever my thought process was at the time.

Saw her, blown away by how beautiful she is(she has a bf now). After days to telling myself to just drop the whole thing and forget about her. I send her a message asking how she's been. Exchanged a few general messages about each other, conversation itself wasn't really awkward, but short-lived. She hasn't replied to my last message and probably won't.

Problem is, can't stop thinking about her; it's been a couple of months. I know it takes time to forget about things, but I feel like I'm going about forgetting her in the wrong way. I stay social with my friends, go out for drinks, play video games to keep me occupied but I always end up thinking about her again, clearly I will most likely not have a relationship with this girl, everything is just against it. Where she lives, she has a boyfriend, we don't talk to each other, etc. 

Obviously if her and I started something it'd be great, but being a realistic person I know that's unlikely. So question to you guys is would you keep at it or just drop the whole thing? if it's the ladder, any tips on what you guys do to keep your mind off a certain person?
