J., You sound like such a nice person. My suggestion is to ask her ahead of time if you may have done something to offend her? Then explain why you are asking her that question and that you would very much like to have a good relationship with her. Please don't get me wrong I am by no means putting the blame on you for this situation. I just know that sometimes people hear things and misinterrupt them so maybe that is the case here. You will never know if you don't ask her and I have a feeling it will continue to eat away at you since you are such a caring person. If that doesn't work at least you know that you did everything you could to solve this problem.
