Thank you for choosing sex over friendship. Now I know where we really stand

When you have a friend who knows that their boyfriend/sexual partner (I don’t know what to call him since he’s getting married to a different woman) is lying about you, at work and is telling you that they are going to do everything they can to get you fired what would you do?

I expected her to at least explain it to the guy outright that I was not saying those things. Instead she listened to him lie again saying that I chewed him out at work when in truth it was the other way around. I’ve been feeling since that day like I’m going to throw up from the stress that he is causing me.

Right now instead of going out with me like she had said she was going to, she instead needed to comfort him in his worked up state. If that guy ever shows up at my house again I’m going to do what she was supposed to do and explain to him that I did not do anything that he’s telling everyone I did. I don’t even know anything about it. So either he should stop being angry or he should back down and leave me alone. He’s creating a hostile work environment for me and if he really wants I’ll go to HR and explain that to them. It all depends on what my friend will back. Sex or friendship.
