David, 53, and Shannon, 53, discussed their rocky relationship while their daughters, Stella, Sophie and Adeline, made her a birthday cake in a new preview clip from an upcoming episode.
David began the conversation by bringing up they renewed their vows for Shannon's birthday just a year ago, and she admitted in her confessional it was "the greatest gift of all."
"So where do you think we stand a year later?" Shannon asked him.
"To be honest, I wish things were a little bit better with us — a lot better with us," he confessed after stumbling to find words. "The last six months have been very stressful for you."
"I don't do well when you're very stressed," he revealed. "Cause I essentially pull away when you're stressed."

"Yeah, I'm stressed about Vicki," Shannon affirmed. "Cause I didn't know what — how her allegation — if it was going to come out and how it would be received."
RadarOnline.com reported Shannon's RHOC costar Vicki Gunvalson alleged David beat Shannon during the season 10 reunion. Shannon adamantly denied her claims, but gained 40 pounds due to the "stress" of having the claim aired on television.
"Right, it didn't bother me but I know it certainly bothered you and there was nothing I could do," David said. "I couldn't convince you to let it go."
Shannon then blamed herself for their current marriage issues, and David tried to reassure her it "wasn't her fault." He tried holding her hand and saying they could continue to talk about it if she wanted to, but she just looked down in sorrow.
Radar exclusively reported the couple has been trapped in a "miserable" marriage since David cheated on Shannon in 2015. They aren't divorcing just yet, as David "loves the fame" that comes from the show.
