Puzzle Complete, No Thanks To You

I've spent the last two years remaking the puzzle in my heart.

I tried on my own for a while, but couldn't find a place to start.

..

Rock climbing with no place to put my hand next

My hands are sweaty and I could plummet to my death.

I felt a presence above me like a harness ready to catch me if I fell.

You knew just when to catch me even if I didn't tell.

You gently picked up all my pieces scattered around

And eventually found a place for each of them to rest.

Your talent of fixing me was then put to the test.

However, there was still one piece missing.

You thought you were finished and that my heart was new

So you left my life without a clue.

The piece was the middle

So I fell apart again. 

But this time I knew how to handle the pain.

I put my heart together again myself

Even with the missing piece being yourself.

I always wished you had put the last piece in and gotten to see your finished project, 

But the truth was, to you, I was only an object.

You had deep, dark secrets you only trusted me to keep.

I boosted your now-permanent ego,

So two years later, you could let me go.

I never asked for your help in my stupid cliche,

But I unconsciously gave you the payment you wanted anyway.

You made me second guess and give accusations,

But sadly, a part of me believes that was one of your intentions.
