Dear Lover... I'm not asking much

I don't want to be your whole world.. I just want to be your favorite part.
Yet we're so close to being apart
Where all your promises?? Promises are forever they say
But welcome to reality ..they are broken by you day by a day
Don't blame me now for walking away
I've never heard you begging me to stay
Dear Lover I guess I haven't found you yet
I'm leaving now before I realize how perfectly we both fit
