Anonymous Confession

I had a partner that shared a friend group with me.
We ended up leaving each other. Afterwards, my ex made decisions that made everyone side with me. Now, they're gone and its just me and my friends.
My confession is that, despite my ex proving their lack of character, I don't feel like my friends were right to side with me either. I feel like maybe I'm not great. I know my mistakes, and the areas where I lacked.
Also, the pain of losing someone I considered to be my best friend still hasn't fully subsided. I hope I never see them again, but there are also days where I miss them dearly.
