Yeah...emails can be a real problem. It's so easy to read the wrong thing into them. If you only have two days until you see her, can you try to just let this sit and bring it up in person?

Try to avoid apologizing for your reaction or non-reaction to her disclosure and just focus on the change in tone in emails you picked up on. You have enough on your plate with your own stuff, and are paying her to help you with it, that you can't take on a social responsibility for her feelings. It's not a social relationship. She is there for you, not the other way around.

Good for you for caring, though. That sounds like a breakthrough. Celebrate that.
