I can only tell you the following from my journey through MLC. Maybe wonka will have a different take.
I knew with every ounce of my being I made it through the tunnel. I was changed, I was molded into the person I was supposed to be. I assumed and thinking now probably wrongly that everyone on the outside would know it too. That assessment may be wrong.
Our kids have told me I was different after the tunnel. More understanding, more calm more positive.
Internally you just know you made it through. Hopefully she can convey that to you in her actions if not verbally. My opinion is if you make it through MLC and accept the journey for what it is, you won't go back...you fought your demons and you put them to rest so your life can move forward.
Based upon some of the things in your conversation, my opinion is she is not totally out but she is more than 75% through. By getting to 100%, you don't question some of the things she still questions(again, my opinion only)
When through, your words and actions are much in alignment.
