I think one of my best friends thought the same thoughts. We did go through a lot together until our mid 20´s now. Then suddenly no contact anymore and I think your reasons for making yourself a priority and so on was one of his reasons. He went to a school at that time and the school taught things about being mindful and how to be a mind "teacher" so to say. However, please do not forget to inform your closest friends about your journey and how you think it is better without them in this stage of your life. I got crazy when he "left". However, I think and hope he is happier now.
