When Caroline Manzo famously declared her family "thick as thieves" on Bravo's Real Housewives of New Jersey, her sister, Dina Manzo, took the statement to heart.

Despite an ongoing feud that continued even after her season 2 departure from RHONJ, Dina tells Watch What Happens Live's Andy Cohen Sunday that she's still holding out hope that her relationship with Caroline will return to normal one day.

"I'm obviously not going to get into the reasons, but. . . we're all on a life journey and sometimes people's energy doesn't vibe," Dina admitted of her tensions with Caroline, who has said that the feud began when Dina alleged that her sister didn't support her post-RHONJ endeavors. "We're just letting it sit . . . It doesn't mean you hate the person or you wish bad for them."

Dina also dispelled rumors that her ally, Teresa Giudice, came between their sisterly bond. "I know this pisses people off, but Teresa had absolutely nothing to do with it,” she said. "I kind of distanced myself from everybody. So I don't know what they're talking about. Maybe something went on that I don't know about."

Although Dina admitted that her strained relationship with Caroline is "weird," neither sister has counted the other out just yet.

"I can guarantee you two things: one, it's going to be OK one day, we're going to be back to normal," she vowed. "And two is as weird as things are, and I'm not gonna lie they are weird, if either one of us needed each other we would be there in a heartbeat. That's where the family bond will never be broken."
