So I'm rubbing my hands with glee over this, as it's the first opportunity I've ever had to post in AIBU. Granted it's incredibly petty but we're both very keen to know who's in the right.
DP and I are getting ready for a (very rare) night out. I am wearing a navy blue dress but think it might be chilly where we're going so I try on a little black jacket and ask him what he thinks. DP replies "I'm sure I remember you, or someone like you saying black and blue don't go."
I make a 
face and say "how d'you mean someone like me?", and he replies "dunno, you or some other woman"
Now I'm not suddenly wracked with jealousy or self-doubt or anything, but I do think that he could have conceded that it sounded a little bit dodgy and worded it slightly differently.
So there you go - a very minor AIBU, but then again it seems like lots of them are. Please settle our debate!
