Ok. Let's presume that she is trying to manipulate/blind/soften.

In the future, my reactions should be what?

I'm keeping in mind that one of her ongoing themes is that "we had no affection or sex" so if I refuse to participate in her games (don't touch her or engage in her inane conversations), would that also reinforce her view of me and our marriage?

This is about "one person can change the dance." So I don't want to iolate her more. (yes, the affair fills that neeed.) But could she also be testing?

How else should I change?
What do you suggest I do in the future about these scenarios?
