Glad you updated. I posted on your sitch before Christmas because I had been following yours given the similarities (in particular, the BD date, mine was April 2016 with in-house separation ending July 2016).
By and large, I expect most here would say you have DB'ed very well, applying little or no pressure after the first month or so. I can't recall one instance where you have posted something that may have confirmed for her the decision to leave, i.e. you insulting her, making her feel guilty, a heated argument in front of kids, etc. You also had a WAW as far you know, not a WW (although I understand she is now perhaps in a relationship of some kind but didn't at least for the first year, maybe longer).
Nobody here is clairvoyant, and I don't even know if you want to hear this now or would still consider R after almost 2 years...but I predict your W comes back once you are in a relationship of your own and sees another woman raising her children.
Don't you find it interesting that she still hasn't served you with divorce papers?
