I'm 38 and I have no interest in having any friends. My life is so busy and I just don't care nor want to listen to anyone else's issues and I don't want to explain all of my life to someone else. I am best friends with my mom. She's the only person other than hubby who I want to talk to. We go shopping, vacations and love to hang out together. Although this works for me, I don't know if I am modeling good behavior for my kids, ages 9 & 6. Is this normal? Any advice?
