So sorry to hear this. My son's best friend left on his mission three years ago, and in the year he has been back, they have not really reconnected. He (the friend) did leave to go to BYUI, but there are few texts, calls - when he is home, not much time together. He has, fortunately, not pressured my son at all about the church, and I am relieved that he is not engaged yet, but we do miss him.
