I'll follow NMMNG whatever she thinks, but what I talk about is relevant to attraction.
MRP says "do not talk about Fight Club" and has NMMNG in the side bar.
NMMNG says on p. 18 "If you are currently in a relationship, I encourage you to ask your partner to read this book along with you."
To me it seems like bad advice if she has lost attraction to your faggot ass. If she is still attracted, talking about NMMNG won't increase that much, if at all, for most women. My guess is, it's probably unnecessary and hazardous.
Glover is a smart guy, but I think he missed the boat in this one instance. The only time it might come up usefully is in dread where she says "you're changing, what does all this mean? What's happening?" And handing her the book would be the answer to the comfort test, but only if she's on your side.
I think I know what guys are going to say here: "she's never on your side, she's on her own side."
