I haven't caught up with your thread, so what I will say is based on the information in your post......and on how most WAW's feel. Please don't look at this experience as progress in the MR. And for sure, don't expect her to act any closer, nicer, or loving, due to her allowing you to comfort her. She wanted somebody in her corner and you were there. What I'm saying is to be careful not to place any expectations on the fact that she had a weak moment. Here's where a lot of LBH's mess up. If you start acting all "happy-like".....it's going to tick her off and she'll start showing you how it's far from back to normal.
If you see where she's making slow steps toward you, then that's great, but this emotional breakdown and her letting you comfort her probably means nothing.
Progress cannot be based on her emotional moments. Just like you can't do that if she happens to be nice to you. It usually doesn't mean anything.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
