i am on the side of the poster who reminded you that therapy is about you and not about your therapist.

I think it normal to wonder about your therapist, their interests, and their life away from the office. Some need to set up boundaries for whatever reason though and we need to respect that. It is their choice whether they divulge things about themselves not ours. You might have to readjust your expectations about that. You don't need to know all about them to be successful in therapy. I realise this is a difficult thing to accept but I am pretty certain that the more you concentrate on your needs the more positive will be your therapy. I think it fair to explain your difficulty this presents to you. A good therapist would acknowledge this and encourage you and coach you in some manner to get past this.
