Camille Grammer isn't the only Real Housewives of Beverly Hills star whose marriage is on the rocks.

When Taylor Armstrong, 38, invites costar Kyle Richards to join her for lunch, the reality star breaks down the moment she begins unloading her relationship issues.

"As your marriage grows you start to realize all the ways that you're different," Armstrong says. "We're so disconnected and I don't know what to do to bring it back together."

When Armstrong confesses that she feels more like a "business partner" than a wife, Richards, 41, attempts to console her friend.

"He's so lucky to have you," Richards tells her. "We all deserve to have it all. Anybody would be lucky to have you."

The Real Housewives of Beverly Hills airs Thursday at 10 p.m. (EST) on Bravo.
