your wife has a work husband, she refers to him as such in your presence
there was an office party
they took pics
work husband puts up pics, tags wife
wife shows you, you lol and joke with her about it. not saying "this isn't cool." (if you did, you haven't said that in this post)
your brother hits you and says "they a cute couple" jokes jokes jokes
now it's "is this a violation."

okay, so given that you didn't care until your brother said something. mind you, in my first post I said what are the comments others are leaving, how is that being handled...which you didn't answer. but in #6, you care about what others have to say...not about your brother while in the OP it's not about what others said, but your brother.

so okay.

i got it wrong but that's how you presented the story.

COOL.
