First of all, do you know exactly what the deal breaker in the M would be for you? If you aren't sure, then you may have to decide. Perhaps you don't know "until" it happened.
I have to remember my state of mind when I was in that WAW mode and if my H was to say anything to me that sounded as if it was a threat or a "dare" then I would react. I may not say anything to him in a reaction, but in my deeds. I will get back to you in a little while about this, but be let me know if you are sure about the what the deal breaders would be to make you leave the M.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
