Just my humble opinion now , I think the current events could be looked at several ways. Firstly your EXW still cares about you ( and will continue to unless something drastic happens ) and will want to be your friend. Also I would Imagine she regrets how the M came to an end and her actions before the end.
Secondly , you have been on your journey though this and have grown as a person. NC helps tremendously with the healing because your not able to analyse the WAS. Maybe the new stich is a reflection of you and your ability to control your feelings and be more accepting of the reality of what is.
All of the above is my take and I'm far from an expert. I also think Huddy has made a good case for the fog of MLC lifting a little but 3 years isn't that long in MLC.
