Shannon Beador revealed that she caught her husband David having an affair in April on last night's episode of "Real Housewives of Orange County."

"At the time when it should've been the best year of my life, he started an affair," Beador revealed at couples counseling with David. "I caught him whispering to this person on the phone and I suspected something was wrong...I just knew something was different and I was told I was crazy...I knew."

Beador also said she discovered hotel receipts in David's briefcase, which helped confirm his infidelity . 

Before the revelation the couple was praised by housewife Vicki Gunvalson for working through the highs and lows of their relationship on the show. 

Although Gunvalson may have regretted her words after learning about David's affair, the Beadors are still trying to make things work. 

"Divorce is not an option, it has never been an option for me," Beador said in the episode. 

"The Real Housewives of Orange County" airs Mondays at 9 p.m. on Bravo.
