Time Heals?

I know I have to stop
But a part of me hangs on.
I know I have to forget
But the memory is to strong.
Sometimes there was nothing there
Other times I think im wrong.
Quiet honestly, I think im over you...
But that's what I said a week after we were through.
Why is it any different this verse?
Is it because time heals a broken heart?
'Cause if you ask me,
I think I've gotten worse.
