"It is really difficult to ask for anything out of these conversations about US since she continues to express her desire for a D and is not very open to talk about much else in respect to US."
How are you and I married to the same woman? This could be part of the problem.
From WAW this am, "I'm not interested in working on the M; I want to be your friend, not your wife."
Your W will be a very good mood, when she sees you, having just spent enjoyable time with OM. Or she may be pissed you are cutting into OM time. One thing we know we are not good at, is trying to figure out their moods. Be your "new" self. Don't be a babbling cool friend. If she asks something, tell her. But do not explain and do not offer more information.
