During dinner, Jordan didn't explicitly tell Cory about Rachel's affair and had merely hinted at it indirectly.
During the meal, Jordan had also intentionally or unintentionally brought up that topic.
Basically, the trio had reached a consensus—regardless of gender, once a cheater, always a cheater.
The actions to take after catching a cheating spouse are either to decisively choose to get a divorce or to turn a blind eye to their infidelity and date other people too.
Cory was obviously not the type who would cheat on Rachel back and date other women. Being on business trips all the time, he had plenty of chances to do so, but he had never been unfaithful.
He was very loyal to love and marriage, so to him, the only option was to get a divorce resolutely!
Cory said, "I can give you the house and the car but don't think of getting a single cent or shares of the company."
