that's so wonderful FMSA!
Contrats to you... . and thanks for coming back to share your progress!
I am not too far behind you and feel I am in the death throes of the acceptance stage and very close to personal freedom. I also have begun to feel exactly as you do. Everything is clearer or sharper.
I think it comes down to being more in the moment and less in a state of PTSD or FOG
For me, the need to know dimished and it was what it was. I stopped being stuck in 'understanding' and accepted all of it.
My most recent posts have been about topics that help me get more certainty about my own issues and how well I have addressed those, and less to do with my ex. I think that is a final stage in the healing and even managed to go out on the weekend and a few hours into the evening realised I had not been looking for him. Because we live in the same town, when I go to our old haunts I have been dreading a run-in. But this time I had not even thought about him and was instead just in the moment and having fun.
