I'm going to ghost one of my best friends
What makes you want to ghost one of your best friends?
I saw that behavior on a website called Linkedin.
It does not seem that you have a good reason to end a relationship with one of your best friends. You should consider what you have  to lose or gain by ghosting your friend. You could ruin a friendship that you're not ready to let go of.
People are complicated but they haven't done anything wrong to me and I still want to ghost.
Do you really want to end potentially good relationships for no reason? How would your best friend feel getting betrayed like this? Perhaps you can just tell him how you feel, maybe he'll be able to help you.
