It's not you

You're trying to hold on to the one you knew,
But I am so over you,
I will not be waiting around for you to come to me,
I am no longer waiting at your door, as you can see,
So leave me alone,
I'm better off,
I'm just gonna brush you off,
So don't try to fix,
What you missed,
I've found someone new,
And guess what Hun,
It's not you.
