Wrong kind of guy......that wont stop me

I really cant explain
y i am in so much pain
and how i go insane
every time i here your name
but yet u treat me like shit
but yet i handle it
no matter what i crawl back 2 u
i don't know what it is that u do
that makes me put myself in this position
and makes me make the wrong decisions
people tell me i shouldn't mess wit that kind of guy
especially if he makes me cry
but know matter what they all say
with u i will still stay
