Letting go isn't so easy...

Whenever i try to find something new
and when i try to let us go,
my mind wanders back to you,
and i try not to let it show.
you're the only one who understands me,
the only one who knows who i am,
you're the only one that really sees
and understands just where i stand.
I've tried more than once to let go
tried more than once to be so strong,
tried not to the the tears flow,
and yet every time I've been wrong.
you're the only one that has my heart,
the only one who can make me go weak,
you've been the one right from the start,
the one that makes it hard to speak.
i know i really should let go of how it used to be,
but it get difficult when there's still hope,
that someday you will be with me,
even when I'm on this downhill slope..
