ur ex sounds like me -.-!!
i also told the same thing to my ex.. i wanna be single..
u knw wad.. i hate he smoke..
b4 this i wanna together back with my ex..
but he said sth that really pissed me off..
he posted this in his twitter
" if you don't love me at my worst you don't deserve me at my best"

Craig y u wanna ask her such question?
That question really made her angry because this shows that
you don't trust her..
in bf-gf relationship.. trusting each other is very important.
For me if I heard such words, I might have this tot..
1) OMG, in your heart i'm that kind of girl..?
2) u hurt me so much..
3) u broke my heart again.. i cant accept u anymore..
May I know,
1) Do you really loves her?
2) Why would you bother she has done anyth with another guy or not?
3) Do you really wanna together back with her?

Maybe you should just buy some flowers and find her .. talk face-to-face.. to try tell her something.. like
im sry ashley, i realised i cant live without you..
pls forgiv me.. i promised i will try my best to gv u happiness..

Hope it helps.
