It sounds like you are in much better shape than I was. What threw me off was the length of your posts in this thread. It showed the kind of obsessive focus I had on what my ex was doing or not doing and what it all meant.
I was referring also to that segment where you refer to your mental state a year ago. These kind of people are truly toxic to be with in an intimate relationship.
Focus on your healing and not on her. That's the best advise I could give.
