IMO, asking an entrapping question to try to prove a point suggests a manipulative tactic. The fact that name-calling and walking away is the response only tends to confirm that suspicion.
Hearing others' thoughts and opinions, even ones with which I disagree, is always okay with me. And I have expressed my own views as well, albeit not as clearly or effectively as some have liked. There seems to be a low tolerance here for different perspectives. Since my experiences are different from many expressed here, I believe I do have things to learn from understanding them. I also believe that my own thoughts have some value.
Dealing what to do when marriages become hurting and troubled is a complex and challenging task. There is no one-size-fits-all that I have ever seen, which is why I believe MWD advocates trying things and "monitoring results."
