I'm in the same boat.
It was when my son begged me to never call my friend again that I listened.
I miss her hilarious sense of humor, but even that became too mean toward me and toxic.
So, that friend I shared a lifetime of experiences with doesn't even really exist anymore.
I feel better without her upsetting me, and cutting her out of my life needed to be done.
Sometimes, she still sends me texts as though we are still friends, and I don't respond. She doesn't even care...she's so nuts.
