-since day one

[Flos Campi]

Hi litQueen! I really like this new edit; it's definitely an improvement over the original version.   Most of my suggestions are about the formatting, not the words themselves, so it might not be the kind of feedback that you're looking for, but I hope it helps nonetheless! 

Since Day One

It started with you,
This year...
Guiding me through the crowds of people,
Your hand on my back. Maybe add another quote after this line (or before L3 if you want to invert everything) to parallel the "I will not give up on you" in L9. 

This year,
Won't end with you.

Your hand on my back. Maybe join this stanza with S2? (Since I think it's supposed to be the response to L3-4 of S1.) 
Guiding me, Another nice inversion! Inversion seems to be a common technique used in this poem. I wonder if it could have thematic meaning... You may want to consider focusing more on this technique!
"I will not give up on you."
As I slowly lit the fuse And then this line is where you might start S3 if you do decide to join the last 3 lines with S2. Also, you might consider changing it to "you slowly lit..." so that the first real action the speaker takes is when she "ended you" in S4. This seems to fit better with the idea of self-liberation (if I am reading the poem correctly that is). 
To ignite my heart.

I ended you,
And me, 

Us. You might want to consider removing this period and moving it to the end of L15 (instead of the comma). For some reason, connecting the word "us" to "fireworks" seems more concrete and impactful than connecting "us" to the entire simile of the next 2 lines. 
Like the fireworks,
Just a temporary show.
Red and green and gold...
And then only blackness.

We've been sitting on dynamite. I really like having this as the last line by itself. It's almost like an abrupt tone shift from the nearly wistful beginning and then suddenly, with this line, it becomes (either truthfully or facetiously) a little sarcastic. Could this be a protective device on the speaker's part to avoid showing emotion/weakness, or is it a sudden epiphany from the reflection in the rest of the poem? Really thought-provoking!
