TITLE: I [19 M] still love her [18 F]
POST: Generics: we were together 4.5 years. She left me. She was my first **real** girlfriend. We are bound to run in to each other now and then... Can't really avoid her. 

I know I can't trust her, and I know there's a pretty good chance we won't get back together. She broke my trust, lied to me, and treated me like shit in the end.

...yet I still love her.

It's so stupid! It's like two guys are fighting it out in my head: I want her, but I also know better.

It's ruined everything. I can't enjoy anything, eat, do normal work like I used to. I have no social life either--all because this has turned my world upside down.

**I feel like I won't be able to move on unless I can completely get over her, or unless we somehow work things out**

Any help you can give is appreciated.
TL;DR: 
I still love my ex, my life is in the gutter, and I don't think I can move on unless I can stop loving her or unless we somehow fix this.
