I don't have many friends, or close friends for that matter. I am married and have a family though, and I find most of my friends were originally my wife's friends. I'm significantly older than you and I have difficulty connecting to new people and making friends. I think part of my issue is that I have considerable social anxiety and this makes me not want to connect to others out of fear of rejection....so most of the time I just try to "act normal" so nobody picks up on my anxiety. That said, the friends I did have growing up (I had small circles of friends), turned out not to be right for me so I burned those bridges. I just haven't yet figured out how to build new bridges, I can have plenty of acquaintances, just no close friends really....or maybe I have a high standard of closeness. Then again, I believe I am INTJ so I really don't like people or social interactions lol
