Decades

I read some books explaining what to do
When lied to, cheated on, and twice betrayed.
You've broken all the promises you made,
Manipulated till the trees were blue,
And made so many claims that were not true
It feels like there's a sharp serrated blade
Pierced through my lungs. The devil's part you played
Has changed me. I spent decades loving you.

I stand before you here, coming apart,
Preparing like mad for my final bow
(I'll make things work, although I don't know how).
Somebody promised there would be a chart.
With loving kindness in my broken heart
And vengeance on my mind, I'm ready now.
