Why cant you just leave?

Why did you have to come back into my life?
my life was OK until you came back into it.
it hurts to know that you don't like me like i like you.
how am i suppose to deal with that?
i like you to much to see you not like me like i like you.
i cant stand not seeing you or touching you.
all i can do it talk to you on the phone and it hurts.
why does this have to happen to me?
why cant you just leave out of my life?
it is hard on me and you dint understand how bad it hurts.
so, why cant you just leave and not come back?
so all i ask is to leave and just not come back.
this hurts so bad to tell you this but i guess this is how it has to be
