Keep up the personal work. Your wife is understandably concerned about MC as are you.
I believe your FIL urged her to work on the m, and I think your w wants the marriage to work OR for her to be happy elsewhere which is not all that different from what we all want.
You are all you control and from your own (brave) admissions, there's a lot to confront.
Stay on that path in your own sandbox, no matter what else happens, b/c you are already learning that working on your own happiness is helping YOU be happy, now.
And that is just a lot more enjoyable for those around you.
As for tonight, my guess is that you need some armor b/c it's not going to be easy hearing what your w has to say. She has a scorecard and it's a long one.
Keep your helmet on. Validate what is legit -because you want to work on that, regardless of what she chooses. For you.
