Opposites Attract

No, I cannot remember,
No, I cannot forget,
There's this aching feeling deep within me,
There's this painless feeling deep within me,
Now it burns and boils,
Now it cools and settles,
And it never goes away,
And it always goes away.
As you walk into my life,
As you walk out of my life,
It strengthens,
It lessens.
I don't expect you to understand,
I do expect you to get a grasp,
The words that slip past my lips,
The words that never leave my head,
You're always running through my dreams,
You're always out-of-sight-out-of-mind,
And I just want you to go away,
And I just want you to stay.
