I'm sorry to hear about your breakup. Never fun to deal with and I have been there (broke up with GF of 5 years a few years back) and I know how you are feeling.
Unfortunately without knowing the specific details of your relationship and how the breakup went down - it is difficult to guide you one way or the other regarding letting her go for good or holding out hope that you will get back together one day. Lets face it...women are some of the most fickle creatures on the planet. They are difficult to read and understand and yet they expect you to be able to read their minds. During breakups, some women will want space (code for she wants to explore other options) and others will say "you didn't chase after me".
The best advice I can give you is to try to lead a normal, active life to keep your mind off of it. Stay off of social media (it will drive you crazy the first time that she posts a photo where it looks like she is having fun or is with another guy). Instead, make plans with friends to do new things. Don't just go to a bar, get drunk, and talk about her to your friends. I mean go do something new. Indoor rock climbing, fall golf, beer tasting events, concerts, bike riding, hiking, etc etc. it is normal to need some alone time to "grieve" personally, but don't let it define you. If she sees that you are leading a normal, happy life and not sobbing on your couch in sweatpants with 14 days worth of facial hair growth - then you win.
Cheers mate...keep your chin up.
