I think it's about a distancer/pursuit thing for your W. Every time you distance yourself from her she becomes more interested in you. You both seem to fall into that kind of dynamic over and over. You're sounding strong and healthier lately though which is good.
I 100% believe the WAS is lucky if reconciliation happens at some point. I think the LBS are often better off without the WAS. Most WAS seem to have issues with addiction, immaturity, etc. I know that's an anti-DB thought, and I still believe in reconcilation if possible, but if not, LBS will often prob. lead a happier, peaceful, less-drama filled life.
