Ah man, I am really sorry. I have no advice, you have had enough of that already. I think what I would struggle with the most is trusting in the future especially after all of the work you have done. For her to indicate how amazing you have been and for her to do this says a lot about her and what she is struggling through. Therapy maybe but it's going to be a long road. Sometimes it's more about them than you.
Sounds like she wants to be able to do this, give you the opportunity to do the same and you both be ok with it. Such a slippery slope. I wonder what she would do if your daughter was out of the house.
