you should do what you think is right, not what we all tell you to do... I would not go and **** 20 women cause I am not like that, never have been!
You must do what you want, take a miserable week and just be sad and angry but watch movies/series etc give yourself a new Fm challenge or go out and buy a new
PS3 or Xbox game...
Dont drink cause it will probably make you feel worse than you already do, just delete her from everything you have, FB,Twitter, Cell contacts, IM, MSN etc etc and just give yourself a few days to mourn and be sad as it does sound like you really are hurting and I am sorry to hear that, I have never been hurt like that, I seem to end the relationship and end up hurting the person but that hurts me so...
take it easy and we can all sit here saying go **** your brains out, have a 3 some, break in to your chicks house or some stupid **** like that but most of the people saying these things would never do that themselves so its a bit vicarious
I hope you feel better in time, and just remember, time heals all wounds and that is a fact!
