I think she takes on way more than she can handle. She likely had good intentions but just can’t handle it. Maybe her husband tells her that she’s not there for the family in the evenings because she texts and emails all evening. 4 email threads from one person is a lot to read. Who knows how available she is for all this within her home life.

But again not your fault. She’s the one that had to set up realistic expectation from the start. Is she fostering dependency? Making you relying on her all day and night?

This is coming from a person who has poor boundaries between work and home and is there for people responding to texts/emails from them day and night. So I am not a good example of what not to do.

Could you sit down with her and go through expectations and make adjustments. What’s reasonable? What could she do for sure? And she needs to stick to it. One email a day? One thread, not 4? Text but maybe not at night? She needs to commit to what she can really do. Obviously she can’t do what she said she was going to. Some changes need to take place
