I can tell you from personal experience that it is never over til it's over. We separated after he stopped the divorce (3/12)but it just shows things can change. I'm in no place to give advice (I'm new here) but take care of yourself and I hope what ever you want to happen does. In my case I'm still hoping for an R but am giving him space and still doing 180s. I am seeing small positive signs. I think from your timeline I've been going through this longer but it seems like it takes some a long time to figure things out.
Although I find it very, very difficult, I find that less is more when responding to things.
Good luck to you!
