She got back in touch after the divorce and we hung out some, though we were never as close again. In the other case the person had less dramatic but heavy personal stuff and we did resume the friendship years later. Sometimes friendships take energy you don't have. I would give her space for a while, and then maybe an occasional quick text.
Adding: you mention that you guys are "not friend collectors" and I take that as an important clue, actually. I think people like this, with a small number of close friends, tend to be introverted by nature and when life gets difficult or upsetting or profound, they want to process it on their own. That's how I am and how most of my close friends are, and I think that's why I have been through this multiple times with friends. (I don't think it's because I'm not supportive, I think it's more the temperament of these friends).
It's hard but I wouldn't lose hope, I would just put the relationship aside for now.
