I don’t want to shoot you down, but as you may have noticed, this is just the sort of thing for which W has super attenuated ultra-high frequency radar. She can clue in on any probes that might hint of a fault within her. I am thinking it best to let the C bring it up, especially now that W and I are in a calm spot (and if for no other reason than to prolong the peace at home for the kids).
The C has already suspected that W has these OCD tendencies and since she claims to be highly OCD herself, she can just tell her own story and see how much W relates to it.
BTW, stop worrying about whether I listen toyou or not. I do. I may not agree wit hyou all the time, and I may have my own selfish reasons for doing what I do, but I still hear you.
