To answer your question, such a MC will more likely say things like "it might be best for you to find 'you' again," or "I think you need to explore your missed Life Opportunities," or "Maybe the two of you just need some 'space' right now," or some such. Self-actualization gobbledegook.
Based on your characterizations, I personally would not attend. I would ONLY attend with someone who was KNOWN to be strongly pro-marriage, and had experience with infidelity, and would with near-certainty support my marriage if I went.
