From my superman to my kryptonite

You used to always be there,
and you used to hold me close.
you still tell me you care,
but its your friends path you chose.
i used to think you were so strong,
i used to think that you were it.
it seems my thinking was all wrong
and that you're more hurt than you'll admit.
we used to be so good together
and we always used to smile.
we always used to say forever,
but forever faded after a while.
you used to be my superman,
now you're my kryptonite.
everything it seems has hit the fan,
it seems like nothing can go right.
