Rainbow: no, it isn't "wrong". Your T must have made her address public in some form, otherwise you would not have found out about it in the first place. If you feel a bit conflicted about it, like you seem to be, then maybe it's worth taking it up with your T. But only for your sake, so it helps you better understand your feelings and motivations around this. From the T's perspective, it doesn't matter, either way, really. Otherwise she would have kept her home address under lock and key.
