I'm pissed

I just need someone to tell. My fiancé works with this woman and she said she'd f*** him to his face. He politely shut her down by saying he would jeopardize our relationship for anything and she hasn't said anything else. Everybody he works with talks like that, he's a corrections officer. But I'm just pissed and completely shocked that someone can just bluntly disrespect a relationship like that without any invitation. #rantover
