Hi Slowly, I've been catching up on your thread over here. First of all, congrats on figuring out NG's need for QT...my LL is QT also and sleeping in (when you could be working on that 20-point to-do list) is sure a great boost for someone who values that "unproductive" time together!
On the guest list, I hear your anxiety about trust issues. Now, is there another explanation possible here? Unless I'm reading it wrong, a joint dinner party seems like a funny thing to be deceptive about since you'll know all eventually anyway, right? Or are you worried about a habit of lying, even about the small stuff? Anyway, obviously this trust thing is a biggie, and I'm not trying to minimize the impact of it.
