Thank you all so much for your encouraging posts.
After taking the rest of the day to mull over what happened, I am able to appreciate how special that moment was (assuming she wasn't offended), and the fact that she was able to express what she did is pretty huge.... and really validating.
I've never in my life had a relationship quite like this one, nor have I ever met a person quite like her, and so I find I'm learning so so much whenever I talk with her... and words can't express how much I appreciate how patient and understanding she has been with me.
Part of me wants to send her an email further clarifying that I didn't mean for my comments to be directed at her, but I think this one should be saved for the next time I see her.
Thanks again everyone
