Call her bluff

My initial response was that I should follow her demands. But then as I was gathering my car keys, I stopped. My wife was giving me an ultimatum that if I didn't do what she wanted, she was going to sleep with some other guy. WHAT THE FUCK!

I wasn't putting up with this shit! Rather than immediately react, I took a moment. I went to the fridge and got a beer, sat on a stool and stared out the wind at the evening sky as I thought. If I caved in now on this, our relationship would never be cone of equals again. I loved my wife, go she was the sexiest woman I have ever met. But I could not, WOULD NOT, be dictated to like this.

Mind made up, and taking a deep breath I sent a text back:

You do what you need to do. If you fuck him, don't bother coming home.

Then, sighing, I went to watch something on TV and take my mind off my beautiful, adulterous wife.
