Obviously you and your T have a different perception here. If your T doesn't apologize or even mentions something about it in that email, she probably isn't really aware of the effect it has on you. Or maybe even the fact that it was inappropriate. While you, obviously, care a lot about what happened.
I have experienced some similar things and I think that it's important to take your feelings seriously. If it bothers you, it bothers you. But then it's up to you to do something about it (because she clearly doesn't see it the same way you do). You have to bring it up and then it's up to her to try to understand your point of view, to see things through your eyes, and to see where it went wrong. It's hard, but necessary I think.
I've had a hard time doing this and the effect was that it happened over and over again. Because I 'clearly didn't have a problem with it'. Truth was, I did but didn't have what it takes to bring it up. So the frustration built up inside of me and I was the only one responsible for it. We can't expect people to know how we feel without saying it. Until the day I mentioned how I felt... It's all about setting your boundaries.
