This reminds me of some things with my T during his issues. I have been pretty open with him about how it affects me and what I've mostly remembered is: if he's there, he's there because he really can be and enjoys it. It actually gave him some relief to work instead of thinking about his own suff.

Whether or not you bring it up, I place my bet on her being helped by talking to you, rather than he feeling like you "took up space" or something.
