Thank you for your thought-provoking question. Being obsessed with another person’s life, particularly someone you don’t know, is a way of avoiding your own needs. The more invested you become in tracking down the nuances of this musician’s life, the less you have to look at your relationships.
I’ll encourage you to talk to you therapist about two things: First, see if there is a therapy group available that would be appropriate for you to join. I believe a group experience with men and women would be helpful because it will help you be more accountable for yourself and your relationships. Secondly, I think it would be important for you to have a plan to begin dating. The goal here is to challenge yourself. The other side of being addicted to love — is to be avoidant of intimacy. I would discuss these possibilities with your therapist to see if they make sense for you.
