The advice about the message back in the day made sense, but much has happened since then. So, I would second that you don't send her a message and stay completely NC.
I totally understand having the fear about W's wrath and anger. Trust me, I was like that too. That was totally part of my NGS where I never wanted to do anything to displease her and just keep the peace. But, I realized that it didn't give any space to how I felt and it didn't resolve anything.
I have lost that fear in the past months, mostly because every time I think she's gonna get angry with me about something, I remember how she's been a lying, manipulative person and I don't need to appease someone like that.
2018 is around the corner and make it your mission to get rid of that fear and have some little script in your head that will balance that fear out when it's happening.
End the year on being a strong confident Chris, and strive hard in 2018 to build that up and be even better.
