The husband dying and therapist still practicing sounds intense. I remember my therapist awkwardly telling me in passing about one of his cats dying and that seemed to be a pretty vulnerable moment, I can't imagine what impact knowing about a therapist's spouse's death would have. It's a really big loss and personally I'd have trouble bringing up my own average issues if I were told my therapist was facing something this huge.

As for living alone, that sounds like judging the quality of another's life to me. I mean, living alone doesn't have to be miserable. For example, at the moment I'm living alone by my own choice, I'm very happy with this at this point in my life, and I would not want it any other way. But a few days ago, a neighbor whose long-time wife had passed away recently told me how very lonely it is for him and wondered how I manage. I don't think that cold data like this can tell you how happy someone is, but on the other hand you are spot on that therapists don't have the perfect, flawless life that many clients imagine.

It's interesting that you look up all this info though. I wonder if it's just curiosity or if you feel like it helps in more ways to know these things about prospective therapists.
