Gordie - did she ask how you were doing with things? If not, that to me, is the biggest problem and would be a giant red flag. And if she did ask, would you feel safe telling her the truth or would you be afraid of the fallout?
It's good she feels safe initiating a conversation. But at some point she needs to turn that finger back at herself. We all do in order to grow.
I know what your life is like. Lots of eggshells with the live-in. Practice lots of self care.
