Sorry to hear about the GF issues.
Don't worry Dude, the pain will go away...
Never! Just kidding.
The pain will go away...Oh I'll say in about 3 hours( if you didn't love her),
3 days ( if you were infatuated w/her),
3 weeks ( if you really liked her a Lot),
3 months ( if she was a passionate lover),
3 years ( if you really loved her and we're planning on marrying her.)
Otherwise, keep your head up and try to do whatever you can to stay busy and your mind preoccupied. Alcohol only works if you're with your friends and not driving.
I do not recommend taking 3 hits of acid and shutting yourself in a room by yourself and watching the Exorcist over and over again. DO NOT DO THAT!
Just relax and enjoy your freedom. There is a 10 to 1 ratio of women, so that's a plus.
Remember, the ladies want to get married around the 2 year mark and when the 4 year mark arrives and you haven't proposed... they flush you like a dead fish we find in our tanks. Move on!
Take care bro,
Richard
