Initially Jasmine's eyes lit up when Reba told her that she herself is in an ethical non-monogamous relationship.
Jasmine was going to be intimate another man regardless of what anyone had to say but Reba's unethical disclosure gave Jasmine the ammo to proceed and give Gino an ultimatum.
Reba became Jasmine's friend instead of "counselor/therapist" whatever she designates herself as. It's wild that instead of discussing why they are fighting all the time and unable to be intimate with each other they decided to focus on an open marriage. If you watch previous episodes it makes it look like Jasmine is controlling Gino gringo bonito, where's papi?, evidence, report, good boy obedient, "you have a thing with the waitress" etc the list goes on and on. No wonder why he couldn't get it up. None of this is to say that Gino hasn't done any wrong in their relationship either, both of them are incompatible.
And for all the people that keep calling out Rob defending Gino, Gino obviously can't stand up to Jasmine so it's nice to see someone trying to stand up for Gino but it was a little too late.
