Why do some friendships fade without any fight or reason?
I have lost several close friends over the years without any argument or falling out. We just drifted apart. This makes me feel like I am somehow not worth keeping around. Is this normal?
Friendship drift is completely normal and happens to almost everyone. Adult friendships require active maintenance and when life gets busy both people stop investing. It's rarely personal.
Some friendships are seasonal, meant for a particular period of your life. Their ending doesn't mean you failed, it means you both grew in different directions.
