Apparently, they were never your friends. They just liked what you did. Now that you have nothing in common with them, they don't want anything to do with you. If I were you, I'd be glad they are out of my life.Can someone tell me why people who you think are your friends turn their back on you. I thought that I had some friends in NC while I lived there, but when I moved away and changed my lifestyle, they completely wiped me off their friends list. I am still the same person I was then, I just don't don't have the same nasty habits.
This is often human nature. If one person in a relationship improves and another doesn't want to, the one still in the rut will either try to sabotage that person's success or push them out of their lives. In a romantic situation, if the woman improves herself and isn't needy, the man feels threatened. Sometimes when one evolves in their life, the other will follow after a while, and a lot of times they won't.
