Sounds like my dad. He used to complain that I don't call him. Yet when I call, he talks crap. Funny thing is he doesn't really talk crap in person ( he used to but mellowed down over the years). Just on the phone he talks crap. I even talked to my therapist and she said we aren't obligated to call people if conversation is unpleasant. Well situation with dad is different as my parents are together and I talk to mom all the time plus not like I abandoned my dad, i see my parents, I just don't call my dad.

Why don't you just stop calling your friend. Life is too short.
