ilikecats, it sounds to me like an emotional attachment. There are boundaries with a therapist and they end after your appointment. They need to decompress to be able to function to allow themselves to help others. Looking up their house and driving by it is a type of stalking and it is not good. It also shows a slight obsession and dependency on your therapist. I would not tell them and i would not do it again. Rather discuss boundaries of a client with a therapist and what is acceptable for detachment. They help you process your problems and transfer the problems so you can work through them. By looking up their house you are undoing the transfer work you are to be working on in counseling. I hope you discuss detachment and transference with them. And leave it at that, tc
