NM, you're not trying to save your marriage right now, you're trying to enjoy yourself! Get your groove back, lady!!!
Uncensored/unsolicited advice from Mrs. A: forget the ring! You know where to find it if you *really* want it. For now, let Zoobrew want to see you *without* using the ring as rationale! Say, "Oh, Zoobrew, I was planning to wear it out tomorrow night (because it really is soooo nice), but I found another one that looks just as good, so I'm fine. Whenever...."
And he'll say, "Ok, NM, well like I told you, this is a really busy week for me. I have a lot going on, so just be patient. But I promise to get you back that ring. I wouldn't want to deprive you of the symbol of your luckiness!!"
BUUUTTTT... then he'll be like, "I gotta get that ring back to NM sometime, I should call her." And then you'll chat again and tell him how nice it was for him to call because you hadn't really thought about the ring but you WERE wondering how HE was doing, and before you know it the ring will be the farthest thing from either of your minds!!!!!
You're in the fun part now!!!! (Nothing more, nothing less, right?!) And lucky for you, it seems like you've found a willing accomplice!
