Now I am not a sucessfull DB'r but us Kiwis need to help each other so my 2c worth , better make that 10c as there is no 2c any more.
Thats a pretty big baby step IMO . She asked you if there is a way back. I think you have done well and let her know the door is a little open but its going to take time. Now she needs to do some of the work.
Try not worry abouth the hurt and betrayal stuff right now , plenty of time for that later. If your true Goal is to save your M then its going to be one small step at a time.
She asked you for Coffee , thats great , perhaps you make the next invite. it looks as though she is wanting to have a look , just take it slow and reward good behaviour !
