I attended my dp's work christmas party. He has a colleague who he's worked with for a few years and has admitted that he finds her attractive. To be fair to him, this only came up during banter/ a game with friends. She is single and very attractive. Clearly has the hots for DP.
When at the Christmas party, people got very drunk. I don't drink. DP's work colleague didn't realise I could hear what she was saying, but she told DP that "if she makes even one wrong move, you know where to find me".
I asked DP what this meant. He said that they were joking that on paper and in another universe they would have been married. AIBU to think WTF?
