Many friendships have broken up on Bravo's The Real Housewives of Atlanta and it looks like Kandi Burruss' bond with Phaedra Parks is next.

NeNe Leakes Talks Qutting 'RHOA' I've Been Offered My Own Show'

In a sneak peek of the upcoming episode (to air Sunday March 8), a disconnect between the ladies is revealed. Burruss is talking to Kenya Moore (one of Parks' arch nemeses on the show) and Cynthia Bailey the night after Parks attacked Moore for bringing up rumors that Parks is cheating on her husband, Apollo Nida.

Burruss tells Moore and Bailey that she "tuned out." When Moore asks if it was because she knew the rumors about the affair were true, Burruss kept quiet.

Apparently Porsha Williams has issues with Burruss staying quiet the night before during the altercation as well.

She lets Parks know, "Kandi should have been more vocal," when it came to defending her against Moore.

Parks agrees, "It's very odd."

NeNe Leakes also notices a distance between Parks and Burruss, who were once a very tight-knit bond.

"You and Phaedra have not been close."

Burruss lets Leakes know, "I have been going through my own [stuff]. If she's having issues she's having them in her own head."

But Parks isn't the only relationship Burruss has hanging in the balance. She and her husband, Todd Tucker, go to counseling after experiencing several riffs in their marriage. Celebrity therapist Dr. Sherry asks Tuker if he's "lost interest" after Burruss questions him about cheating.

Check it out.
