So I'm finding that many of my adult friendships are somewhat asymmetrical--I'm contacting that person more than they are contacting me. I'm looking for a good book or thoughtful, longer article about adult friendships, as I've never had great social skills and I need to think about them in a thoughtful, deliberate manner. Thanks for your recommendations.
I am in my early fifties, and married. Some of these friends are couples, and some are old college friends.
