Does it not bother you enough that you already scared her, to respect her wishes and leave her private life alone?
Do you want to lose a T?

She has already been fairly clear about this issue and yet you are choosing to break the trust of the relationship and cause fear in your T.

While clients are normally curious about their T's lives, most are respectful about the boundaries that are set; and especially if the T already said they were scared by previous behaviors.

I would suggest you do some guided imagery imagining what it would be like driving by T's home. Or imagery about what it would be like going into T's home. I would also highly suggest that you do not do it, but talk to your T about the desire.
