LIfe blows

well dude i've been there and done that, with her being a friend of my friends. Theres two ways you can do make yourself feel better

1- find new friends
2- make her feel unwanted around your friends (i did this because my friends never liked her anyways)

Honestly it sounds like the relationship was based on sex (like mine was :( ) in time you will realize that and it will hurt more, just a heads up. if it was physical (must have been if you fought so much) then your gonna realize you are totally wrong about how a good relationship feels and i think that is the worst part of it all :(

Best way to make yourself feel better is to spend as little time around her as possible. seeing her around is only gonna make you remember the times she was in your arms yada yada yada. you know what i mean.

Get out driving, fool around with some other girls, maybe find new friends, try spending time doing something you love but haven't had much time for and most of all stay true to yourself!

Dont go back to her even if shes made a mistake about the break up, it only means the other relationship she was getting into didn't work out and she doesn't want to be alone. Stay strong, be the man, suck it up and go **** another girl! (joking about sleeping with another girl)

oh and remember it takes time for the pain to go away, sometimes months, i'm just getting back to myself and i've vowed never to let a woman put a damper on my life like that again. Next time you see a girl like your ex coming along keep your distance! make sure you learn from your mistakes
