This is the 3.5 year follow up to the 101 version of this post.

In the previous version, you learned how to pressure flip and change the paradigm. It's not "I'm not going to have an affair", but "Don't give me a reason to have an affair." You put it out there honestly that if and when you have an affair, it won't be a surprise to her. She can always trust you because you have enough faith in yourself that you see no reason to bullshit.

Good job!

Here's the 201 version.

Q: Are you having an affair?

A: Are you sure you want to know?

As a warning, do not skip the 101 version and go straight to the 201. Because if you do, the response you're going to get back is "Of course I do you fucking prick. Watch me divorce rape your ass."
