Pur, I think you're doing great, remember this is a process. Detachment doesn't happen overnight. It's taken me 10 months to get to a place of pretty good detachment, but of course the first 6 months of that I was trying to stay attached.
It does seem that you are still living inside his head much of the time. If you can work on turning that off, it will be so helpful. When you start the "what does he think" or "what will he do" stuff, change it to: he's gone, that's not my problem anymore.
It's a brutal reality but it helps.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
