The Married at First Sight Season 10 couple's relationship was caught in a downward spiral ever since their honeymoon in Panama when Zach told Mindy on several occasions he wasn't attracted to her and they lacked intangible chemistry.
Mindy never gave up on her marriage despite her bruised ego, but Zach threw his walls up and kept his distance from his wife. He even refused to move in with Mindy in Washington, D.C.
After catching Zach in lies and growing tired of being the only one to put effort into their relationship, Mindy decided to end her marriage to Zach once and for all in last week's episode of Married at First Sight.
"Have you learned anything about yourself and how you handle conflict?" host Jamie Otis asked Zach on the Wednesday, April 1 episode of Married at First Sight: Unfiltered.
"Yeah, I think with Mindy being so opposite of me -- like, very opposite -- I didn't know how to address things head on," Zach explained.
"So a lot of the reasons I do talk in circles is because, in previous conversations, the direct words were misconstrued."
"And so, I was super cautious about what I was saying all the time," Zach added.
In a late February episode of Unfiltered, Zach explained that Mindy had "a really tough response" to him being honest with her about his feelings -- or lack thereof, in this case -- and so she blurted out, "I want a divorce."
"And then the next day, she was like, 'I think we should see other people,' which was kind of alarming for me," Zach claimed at the time.
Mindy disapproved of Zach starting a friendship with her close friend Lindsay behind her back, and then she caught Zach in a lie when he was trying to protect Lindsay.
"I told myself I was only going to let myself be disappointed like that one more time and that's it, so I can't subject myself to that. I'm sorry to say but I don't want to be in this marriage anymore," Mindy told Zach in last week's broadcast.
"I don't know what to say. I feel like I have a lot to say but I don't know what to say," Zach replied. "I feel with the lack of transparency, it put you in a position where you had to make this decision, but I don't think I expected it."
Mindy said she wanted to make her marriage work so badly that she had been willing to pretty much do anything.
"But what I've learned is no matter how much I wanted it, a marriage is not about one person and my husband did not show up to be any kind of decent partner," Mindy griped.
