Is she at any point bringing up the MR? I think you should wait for an opening. I am not sure if you should initiate it and apologize for everything you have noted. If she's hurt and fragile right now, maybe be more careful because she might just need time and space rather than you saying anything.
One thing you can do without apologizing, and can be a 180, is if she's making little comments that you were taking the wrong way in the past, maybe clarify in a positive way or ask a question about it while communicating you are trying to understand what she is saying. I think that might be more powerful because she is seeing in action rather than you saying anything about the behaviour.
Definitely validate her, but maybe wait for her to bring it up.
Thank you. Great advice! No she's not talking about the MR and and she's also not talking about separation anymore either. I'm going to take you're advice and continue to 180. I will save the validation for later.
