The Most Devastating Breakups In Married At First Sight History

On season 5 of Married at First Sight, Nate Duhon and Sheila Downs had undeniable chemistry at the altar; they also shared the same values. Those similarities, however, were not enough to sustain a happily-ever-after for the pair. The fighting began during their honeymoon, causing Sheila to have doubts about her husband's commitment. "I was all in, so when we got into a dumb fight and Nathan immediately said that he no longer wanted to be married, that sent me into a tailspin," she dished to The Knot 

On Decision Day, they admitted their wrongdoings and vowed to work on their problems. However, they had a devastating breakup when Sheila tweeted that a woman told her she was sleeping with Nate (via Us Weekly). To clear up any speculation, the groom posted on Twitter (via People) in a since-deleted tweet, "Infidelity was not a reason, nor did I ever admit such a thing." 

In response, Sheila wrote on Instagram, "I see that instead of finally operating in integrity, [Nate] chose to continue to lie...He was dishonest and there were women throughout our entire marriage."
