Brother, is there such thing as a best friend? I'm the type of person who thinks that I only allow myself one best friend, but after a few failed friendships, I'm starting to believe such thing never actually exist. Was it because my previous failed friendships? And also, is it true that soulmate can be in a form of a best friend? Thank you very much for listening and hopefully responding to me.

A best friend is just a good friend that you prefer over your other friends. Some people believe that soulmates are assigned from birth. My own view is that all souls can be soulmates if they are pure and selfless. There is no reason why a best friend cannot be a soulmate.
