I had a spiritual counselor and I would drive by their house. I think I did it the first time out of curiosity. But afterwards I would just reroute how I was driving to go by the house, to check if they were home etc. It was not healthy. Looking back, I now believe that this counselor was at times inappropriate. I had been invited into the house once, and for no important reason. After that I had other spiritual counselors and I never even gave it a thought where they lived. I think when I was getting the kind of counseling I needed professional boundaries were easily maintained. If the urge to drive by the house continues there is something more than curiosity going on.
