If you truly need to let go or drop the rope you don't respond at all. Even if you don't FEEL like you can do this, you do it anyway.
If you can't let go and feel the need to continue to pursue, enable her argumentitive behavior, and you believe this saves your marriage then by all means keep responding but do it so where your upbeat and fake. lol
If that question is reality, then it's a test. She's seeing if she still can control you. Not attractive.
You figured it out though... No response is the correct answer.
