Going grouch life,
Not knowing my purpose,
Really having no clue,
Learning more and more.

^^ "Going grouch life?" did I misread that? Did you mean through or something like that? Otherwise this stanza is pretty well written.

Going many places,
Seeing many things,
It changes a person,
I seem to have been getting worse.

^^ The last line here messes up your flow, but the rest and the meaning are nice.

Constantly getting myself into trouble,
The I crossed her path again,
One whole year has passed,
Once I was with her again.

^^ I like how you actually say you are a troublemaker lol. I love that. And its so true :P As for the remaining lines are sweet. This time you didn't direct the piece to her, but you did mention her. Excellent use of variety.

Everything started getting better,
She brought me to my better self,
I had once left her,
She had gotten incredibly sad.

^^ Sad is a very basic term, I would have liked to see a stronger word. And the stuff about her making you better is really sweet. When you mention you left her it makes me wonder how bad things got. But it also shows me that even some of the worst messes can be cleaned up.

I'll never leave her again,
I hated that it hurt her,
I just want her to be cheerful,
I'll always be by her side.

^^ Perfect ending, I love how much you say she means to you.

Through the whole piece, I heard your voice and really felt the love you have for this girl. I think yet again the flow and word choice could use some improvements. Though the style, tone, and voice are immaculate and strong. Amazing job.

4/5
