What have i done wrong? just tell me this- was it the way i acted?

What have i done wrong?
just tell me this-
was it the way i acted?
or the way i kiss?
I hate when we're apart,
so please come here..
we'll talk everything out
and make things clear
I know you're the one,
and i've never been so sure
Im sick without our love
-and your the only cure...
Can we please try it again?
i'll try my very best
I love you so much!
my heart hurts deep in my chest..
