I would suggest that you talk to W face-to-face and inform her that you've received her latest email. Thank her for sharing her views and that you need some time to process all of this information. The pair of you need to step back a bit for a while and acknowledge the fact it is indeed a difficult time for you two.
Then say, "I still care and love you deeply. I do not want to separate but will not stand in your way. Right now, let's focus on Thanksgiving holiday and spend time with our son."
Then walk away. She will try to engage with you. If she does, put up a hand and say, "I am tired. This isn't a good time to talk. I'd like to table it for some other time. I want to relax tonight. Thank for respecting my request."
