My T's house was also in an out-of-the-way place. Both houses. I also think the reason was to feel more connected to her and to have a sense of where is when she's not in the office. For me, it's attachment stuff. Probably why I feel insecure while she's vacationing in another country! Or it could be just plain curiosity. What do you think is the reason you want to see her house?

You don't have to decide now whether you want to tell her or not. When you're sitting with her, in the office, you will make the decision. Either way, it will work out all right. You'll see.
