The door was left open as she did walk away...

In ruins did i live all in the guise of letting go

Seconds to minutes, hours from the former and days took over what have we now? Months gone by...

I tiptoed to the door, closing it was my sole option...
...but how do I breathe, hence my only source of ventilation?

So i crept back to my former location, sitting down; legs crossed as tho I had become a kungfu master...

...cos the aim was to revenge; get even wit all that did hurt

Buh glory be to God for the reminder that i could get even more hurt in the intended quest to get even

The multiple shattered hearts have to an extent mended

I await to stand up for and to whoever walks in

What's the structure of this poem?
