“I feel that one day you could leave me,” Chris says in the clip.

And while taking a polygraph test, Desiree makes an equally shocking confession about their relationship.

“I settled for Chris,” she says.

The emotional clip comes just one day after Desiree and Chris announced they are expecting their second child.

“We are beyond excited to finally announce that we’re expecting!!” wrote Desiree, 32. “And it’s safe to say after Asher realized he was going to be a BIG brother he wasn’t so happy! (Swipe for pic) Lol.” (In the photo, their 20-month-old son Asher is peering down at a book called I Am a Big Brother!, with his tearful face suggesting that he just learned he’d have to share his toys.)
