Someone else may have pointed this out but looking at his daughter's facebook page isn't googling him himself. This is an invasion of his entire family's privacy. It is unfortunate you felt compelled to do this.

At the end of the day you need to not forget that he is a person too. He has a family, hobbies, activities, and a relatively normal life away from his office. Just like anyone he will have his own foibles too. I think placing our therapists and psychiatrists on a pedestal or looking for reasons to remove them from such is unreasonable.

Try to put what you know behind you. Realise what happens in their own life likely has no affect on your therapy. Start over with your therapist as though you were just getting to know them from the beginning and in this way build a new professional relationship.
