Is it really so bad to drive past your T's house? Your intention was not to stalk but to perhaps to feel connected with her during her vacation, or natural curiosity. You were only looking at a house, not going inside or bothering her. You sound like a good person. If it helps you to feel better, I do something similar, I look at Google Maps to get an idea of how T's house looks like, though I am too afraid to drive past. I also walk to T's office building whenever I miss T and enjoy the soothing atmosphere, then go home with the warm fuzzies. Good luck, I hope everything goes well for you.
