During Wednesday night's episode of Married at First Sight: Unfiltered, Amber viewed a Season 9 clip in which her best friend Raven informed her the night before "Decision Day" he had previously spotted Matt out at a bar with another woman.
Amber bawled her eyes out upon learning that news, especially upon hearing Matt had been "very focused" on this mystery woman at the bar, and Amber broke down into tears watching it back again on Unfiltered.
"I just don't understand why he would treat other humans like that," Amber cried.
"I desperately wish I would have walked away when he didn't come home the first time."
A month into the Married at First Sight process, Matt spent a total of three nights away from his shared apartment with Amber, and he apparently never called or checked in with Amber first.
The very first time Matt disappeared for 24 hours, Amber stayed up all night crying and was so distraught that she had to call into work sick the next day.
Amber felt unwanted, unloved and unappreciated at the time, and to make matters worse, she had found Matt's wedding ring in the drawer of his nightstand next to their bed.
When Matt finally returned home, Amber accepted a simple apology from her husband, who also claimed he had taken his ring off to exercise and had just forgotten to put it back on.
"Like, my gut told me he was cheating this whole time," Amber said on Unfiltered, "and it just sucks that I heard this almost too late."
Unfiltered host Jamie Otis, however, gave Matt the benefit of the doubt by suggesting that although Matt had been spotted leaving a bar with another woman, maybe that doesn't necessarily mean he was physically cheating.

"You don't leave a bar at two in the morning with a girl [just to be] by yourself," Amber said.
Not only did Amber choose to stay with Matt in the marriage after he had ditched her for 24 hours, but she also had an out when each couple was given the opportunity to continue or leave their marriages on "Recommitment Day."
Amber was hesitant at the time to give Matt another chance, but she ultimately did.
However, Amber asked for a divorce from Matt on Married at First Sight's "Decision Day," which just aired Wednesday night on Lifetime. Matt agreed divorce was the best option for both of them.
Earlier in the Unfiltered broadcast, Amber also told Jamie she felt the sweet comments Matt told her as they had enjoyed a "romantic" final dinner at a brewery before "Decision Day" were basically a stream of lies.
"It's hard to know if his words are genuine because his actions haven't really matched the words," Amber explained.
"I think that's why in the moment I'm just smirking, because it's like bullsh-t."
"Matt's full of sh-t! I'm sorry," Elizabeth added, before calling Matt out for disappearing hours on end and not coming back to his shared apartment with Amber at night several times.
"Just the fact that I know he was out and about and wouldn't come home for Amber and he left his wedding ring [behind]. One plus one equals two, and that equals that. He just sucks!"
When Amber had her last dinner with Matt before "Decision Day," Matt acknowledged they had a lot in common and then explained what he liked most about marriage.
"I like having somebody in your corner all the time, having somebody that you know has got your back and you don't have to do stuff, like go grocery shopping, alone, and you don't have to be alone all the time," Matt explained to Amber.
"Yeah, I enjoy my solitude, but that's one of my motivating factors to doing this, is because I did get lonely a lot of times."
Amber smirked at this point in the conversation, and then Matt continued, "Being married, you've got your person to do whatever with. That's what I like about it."
Amber seemed to appreciate the irony of the situation given she had been the lonely spouse in their marriage, always waiting for Matt to come home late at night or at least call and text her when he was gone.
