Reachingout, Don't move out. Stay friendly but withdrawn. You say she's noticed your 180's. How so? What's been different? Don't pressure her about her PA. Read the chapter on infidelity if you haven't already, especially the last section.
Z, Don't give her the book. Go slowly. IF she's willing to read something, give her "Getting Through to the Man You Love." Some similar ideas, but no LRT. Women often love it.But don't push any book on her that she doesn't seem interested in reading. Michele
