Followed your sitch but not really commented and a big thx for your input on mine.
I know this sounds like a cliche but I guess it boils down to how much you love your W and how much you want to save your M (even if it seems lost). FWIW IMO I agree with cadet in that they all say its done..it is script.
But and it is a big but, the dating, retrauville etc all seems like pressure to me and she is backing right off to the point she is crawling in her shell again...when it looked like she had just started to come out. No one here can tell you whether or not to date but your W may see it as an ultimatum, i.e. if you are not working on the M I am going to do this, so make your mind up quick before an OW snaps me up. I don't think you have given it enough time to get to that stage yet...but I know you feel differently.
It still sounds like she is confused, does not know what she wants but her wall (that has show some cracks) has gone right back up. If it is MLC (I know you don't like labels) then this could be a much longer haul than the months you have given it.
Just my opinion AS and you know yourself and W better than we do. But reading your sitch it does not sound like she is done, it is whether you have any patience left to stick with it...because that is the motto here right? patience and more patience and just when you think you havent got any left......even more patience.
Take care AS and good luck with whatever you decide. Your dedication to these forums has been great and you have helped me through some tricky moments in my short time here.
