interesting topic here and nice post!
i have been ghosted by a lot of friends in the past year. i feel like the emotional damage of platonic friendships ending is similar to romantic relationships for me. the fact that ghosting prevents from me doing a post-mortem analysis with the other person in understanding if i did something wrong is very stressful and debilitating.
I have been able to just start focusing on people that match my energy when it comes to wanting to hang out and that has been a nice coping method for me.
