This is your Sad moment , take time out for yourself , lock yourself in the room , and think deep thoughts , DONT go out asap to the clubs & find other women , if u wanna do that with a group of friends sure thats fine , but give it sum time like a nice week , or weekend , the limit is a month for me , but hey take as much time as u need , to recover , its NOT the end of the world for you , i kno u wanna seek vengence revenge , kick the crap outta the new guy infront of her but Dont do it , Dont Run after her , You get urself together and come back on the soical scene in all glory , and she'll look at you from either a far or scretly tell you that u look nice , but ignore all of that and keep it moving on with ur life ...Good Luck
