SA, I am so glad that you feel as if a weight has gone. It is even greater when the pain of the divorce is finally over.
Do not mistrust your instincts - what you were seeing probably were 'signs'. Just as the signs of MLC are small at first, and pass almost undetected at the time, so are the early signs of a reversal of the process.
But it is harder to climb out of MLC than to slide into it, because it involves work, and facing up to what they have done.
I have come to the view that those who have a long and protracted MLC [and may or may not emerge] are maybe better left to sort themselves out. We have put our life on hold, to some extent, as long as we wait for them and hope for the restoration of our marriage. That is the nature of the commitment, but at some point I believe it does everyone concerned more harm than good to go on waiting.
The WAS already knows we love them and have waited. Message received and understood, but still on Planet Zog. And we have pretty much healed and are emotionally ready to take on the world again, and fully re-engage with life. We need to do this when it prompts us. We now love and respect ourselves again, and have decided not to be treated so poorly.
As you rightly say, we are no longer anrgy and resentful. We have accepted the situation and let go of it to move forward.
