You sound young so enjoy life, if she loves you she will come back. If not then they're are plenty of fish in the sea. I split with mine after 13 years, try that one
After the intial jolt its all ok, I am back doing what I was before, back to cycling, going out and just having a good time. You only have one life and by god its time to get on with it son. Some things are just not ment to be.
