'This Marriage Will Be Over!' Ashley & Michael Have Their Worst Fight Yet

This week's episode of the Real Housewives of Potomac was full of screaming and name-calling, but this time, it wasn't just the ladies with their claws out. Ashley Darby's husband Michael tried his best to keep his spats with his wife off-camera, but clearly, that was a fail.

Karen Huger and Gizelle Bryant went on a double date to the go-kart track with their men. It could have been an easy, drama-free night, but no episode of RHOP is complete without a healthy dose of unsolicited advice. Karen took Gizelle's boyfriend aside to find out what his intentions were for the relationship. Dr. Black Bill Gates took Gizelle aside to tell her that she had better catch a decent man before her looks fade completely. Gizelle took it exactly how one would expect, reminding viewers that the good doctor was approximately one thousand years old.

In an effort to save their failing restaurant Oz, Ashley came up with some new menu options, veering away from the exotic game that had previously dominated the offerings. To showcase the food, Ashley cooked up an event where she would invite food critics, bloggers and "the ladies" to try out what's new. Michael was not happy that they were straying from the restaurant's Australian theme, and even less happy that they were throwing an event together on short notice. Ashley would not be deterred.

Robyn Dixon and her husband Juan cooked dinner and let their adorable sons serve it up to their grandparents. Even at the cute family dinner, the tension between Juan and Robyn was apparent.

Karen scheduled a boudoir photoshoot to show off her cakes for Dr. Black Bill Gates. She invited Gizelle over for the event, showing her, THIS is how you keep a man. Ok.

The day of Ashley's restaurant showcase finally arrived, and Michael still wasn't on board. They got into a NASTY argument over the phone, outside the venue, by the bar --- anywhere they could fight, they fought. Ashley called him a "F*****g insane a*****e," and Michael shooed the cameras away, apparently not realizing that Ashley had on a microphone. She told him their marriage would be over if he didn't start cooperating with her on the restaurant. The showcase continued, but will their relationship survive?
