I'm going out each night and having fun would be harder for me, cause I'm an evil bitch :p
And if you screwed up and lost me, I want you to suffer :p

i wouldn't say jelousy is the answer. give her space.

me i'm rather cynical. if i see you sad not moving on i wouldn't come back because i pitty you, i'd feel rather turned off. if i see you parting to show me how quickly you got over our relationship i'd think it meant very little to you in the first place. in either case you would look pathetic in my eyes.

do the things you used to do before and during your relationship. i mean make your feeling clear, say you want her back but don't push it too much. if she realises that leaving you was a mistake she'll return.

good luck anyway
