She would be defensive to a degree, but mostly she would be deeply hurt. She has to answer and comment on everything, so she would start out trying to explain (rationalize) her behavior in a very long, drawn out message, which would be based on her defense mechanisms as an empath (she identifies this way) and diffident person.

It's possible that with some therapeutic work and self-reflection, she may modify her behavior, but that will probably be way down the road.

I feel that the best route to take with her, at this point, is to put some distance between us. I won't be the instigator of messaging, and I won't make plans with her. We already had plans to see a movie tomorrow, so I'm obligated to fulfill that (at least we won't have much time for chatting). I don't have a large number of friends, so I hate to totally lose any of them. I'll see how things go over time.

For me, I realize now, it's more about embracing friends who I find to be mostly positive and supportive, and distancing from those who are mostly toxic and/or draining. I deleted my Facebook account and broke ties with most family members last year, in part, to support that effort. After my mom died back in 2017, I no longer felt obligated to stay in contact with family.
