We just got back from the cruise - I didn't tell anyone about the A, even though there were more than a few moments where I felt inclined to do so. It's just a bell that can't be unrung.

One thing that I did finally decide, though, was that it seems like her family would believe me if I told them all of what she's done since we got married. Her father and I have had a running argument (playful) for several years now over his return policy. My W does a lot of ball-busting with her family, especially with her dad and brother. Once she starts, her dad starts commiserating with me, usually to the tune of:
FiL: Do you hear this? Can you believe what she said?
M: Yeah...I get to live with that!
FiL: I told you at the wedding...no returns!
M: Lemon laws should come into play at some point!
...you get the picture.

More telling, though, was at the end of the last night of the cruise her mother told me that she understood that my W wasn't the easiest person to get along with and that she knew I had my hands full in trying to deal with her, and that she wished she had a magic wand to wave and make my WW a better wife. I've gotta tell you...it was a tempting moment to disclose some of the details.
