The worst part of being Alone

[UnicornRainbowCake]

I have known her for a long time. Unfortunately this is one of those lines where however you put it will always sound a little awkward. You describe this later in your poem, and your poem still stands without it, so cutting it would be an option
I have coexisted and shared moments with her,
Shared a life with her…
But I haven’t befriended her yet.

Yes, I have laid on my bed next to her;
I even have a pillow only for her head,
My blanket is meant to be shared with her, These three lines are so similar, it almost becomes dreary to read through. Try mixing them up a bit
At least for now.
But I haven’t befriended her yet. This is quite interesting

She’s heard my lost “I love you”s,
She’s been dancing and singing the blues with me.
Sometimes she’s given me the tools
To keep dancing during difficult tunes.

She’s been at the tip of my fingers;
Pressing gently, with her strength, the strings of my guitar.
She’s been pressed between my thumb and my index
Transmuted into words: words of love; of what we are. The last stanza is definitely my favourite

I haven't gone in to much detail in novice, but your edits are certainly improvements - well done
