On Wednesday night's Unfiltered episode hosted by Season 1 MAFS star Jamie Otis, Jacob watched back a Season 12 clip of Chris telling Paige that he couldn't focus on building their connection because she allegedly wouldn't answer her phone when he called.
"And the reason why is because every time we get here and we're trying to have a conversation, you have nothing to say!" Paige laments in the clip.
"I don't have sh-t to say in person because you ain't got sh-t to say off the camera," Chris counters.
"I called you five to seven times and you didn't answer. And that feels like rejection to me. I'm going by actions off the camera. I think that we are at a dead end."
Jamie asked Jacob for his take on that clip -- with Paige sitting right next to him -- and Jacob didn't hold back.
"He's just fundamentally screwed up in so many ways as to how he's conducting himself," Jacob admitted.
"After what you've done to her the past however many of weeks, right? And then you're going to come at her for missing some phone calls?!"
Jacob continued to vent, "It's like, 'Come on, dude. What world are you on?' Like, I'm on a different planet too, but it's like, you know, I still kind of know what time it is here."
Jacob laughed and added, "I don't know. That's how I feel about that clip."
Jacob also previously called Chris "a dumbass" and "junior high" among other insults during his previous Unfiltered appearances (and Chris recently fired back!).

While Jacob seems to think Chris never took accountability in his marriage, Jacob has taken responsibility and apologized for many mistakes in his own marriage to Haley Harris on Season 12 of the series.
While Jacob has accused Haley of not being vulnerable or putting much effort into sparking romance, he has taken the blame for harping on negative subjects -- such as Haley not being attracted to him -- and picking fights.
"Do you think the advice the experts have given you has positively affected your marriage?" Jamie asked on Wednesday night's Unfiltered broadcast.
"I think in the moment, the message was good and helpful to hear. But we've had issues so far actually executing on that stuff and actually having progress and growth from it," Jacob explained.
Around the one-month mark of Jacob and Haley's marriage, they were just working on being friends and trying to enjoy each other's company.
"[Becoming friends] obviously can help," Jacob said on Unfiltered.
"You see somebody in a different light when you're doing an activity together. It's just a matter of finding that activity and having both participants be willing to plug into it and have that experience."
