Analysis of Best friend breakup

Everyone thought we would last forever, we told each other everything, we knew almost everything about each other well I thought so until the surprise break up. Everything new and everything old you were the first person to know. If pillars were people, you were one of the stronger ones in my life for a very long time.
What happened I keep asking myself, did I become too much of a problem for you to handle I keep asking myself, did I ruin it? Maybe I did, maybe I did not but considering how dramatic I am, I sure did!
Through hurdles and blocks you had me through it all and through deferent stress levels I got you through it all, we were so there for each other on every step of the way, you saved me from a dangerous hungry lion, when it was about to consume me, you brought your spear to the occasion when it opened it’s mouth to consume me, when it was already smelling my blood in it’s nostrils when it’s teeth were about to be sunk deep in my flesh, you raised your spear and you threw it right into it’s mouth and that’s the day I established you as my savior.
What happened I keep asking myself, for I saw with new surprises in your life that I wasn’t part of it and somewhere some how it was my fault that our situation was that way? Was I not there for you too when you needed me, was I not your trusted adviser when you needed advices oh I think I got it,, did one of my advices lead you into the lion den? If that’s the case I never meant all for all that to happen, all I wanted was the best for you.
A stranger, an absolute unknown variable, that’s me in your life, I have become like those tiny food particles that rich people don’t even notice in their plate of food let alone even know they exist in their plate. What happened, what happened I keep asking myself.
Did I become poison I keep asking myself, or did I lose my mind and became insane. Even if that was the case was I not worth enough like any soul that you couldn’t bring me water or anything to drink to soften my throat in my dark days?
Who am I to judge for to me I am a fixed component, and everyone around me are just variable components that are always moving,, they rise like beautiful sun in a clear sky and during the day they shine bright, well some disappear during the day like the sun being covered by the clouds, but the story ends the same with a sunset either beautiful or not.
I would love to describe our ending as of that of a surprise sunset that disappeared into the clouds and all of a sudden it was dark, and then I knew it was sunset.
I wish nothing but the best for you Miley.  Be happy in your new adventure with your new best friends.
