You and I both know what you did...
You left, and all I can say is thank you, it was the best thing you could have done for me. From once inseparable to now strangers who don't even acknowledge each other on the streets, it took me awhile to get used to your absence and it sure wasn't easy, that is for sure. You will never know the countless nights I laid awake thinking and wondering what I did that was so wrong to make you leave when all along it was never my fault. I only wish I realized that sooner rather than later.
I never truly knew how toxic you were for me until after you were gone... Rather than try and help me become the best person I could constantly be, you pushed me down and always made me feel small. I adored you to the strongest extent and to me, you could do no wrong.
After you left, I hated myself and I was mad for a long time, even though I knew you leaving had nothing to do with me. I hated myself because you DID leave, you were the one person I never thought I would have to worry about leaving, but you proved me wrong. You could and you would leave. I was mad because anytime I would see a picture of you and me together, I would have to tell myself that you aren't here anymore - mad because anytime I would run into an acquaintance of ours, they would ask how you are and I don't want to tell them that I don't know. I was mad because anytime I would get a flashback or think about a happy memory of us, I knew that would never happen again.
After time had passed, I came to peace with the fact that you had left. I came to know that it was for the best and that it was actually a blessing in disguise - that in all actuality, it was the best thing you could have done for me. I no longer feel small and I have come to be the best me I can possibly be. I no longer question my self-worth and I have come to realize who I actually am supposed to be, and who that is... Is nothing like you.
So yes, thank you for leaving.
