Why Won't He Go Away

Why does he stay
He Just won't go away
he is always here
always near
making life painful
every chance he gets
he is with me
and then with her
making it hurt
worse and worse
every time he leaves
i cry
even after knowing
it was gonna happen
and i was gonna get hurt
i still can't stop loving him
he will always be on my mind
no matter how hard i try
he just won't go away!!!
