Elizabeth opened up to host Jamie Otis on Wednesday night's episode ofMarried at First Sight: Unfiltered about how Amber seemed to ignore major red flags in her relationship with Matt, including his "cold" body language at times and his habit of disappearing for hours on end.
"I think she's just really trying hard. She's trying. She's giving it 110 percent, and sometimes you just overlook things and you just try to keep working at it and working at it," Elizabeth explained.
"So, I think that's just what she's trying to do right now."
Elizabeth and Amber's Season 9 Married at First Sight co-star, Keith Manley, seemed to agree with Elizabeth, saying it was clear Amber was "putting everything she has on the line and on the table" for her marriage.
"Sometimes, depending on who you're dealing with, that may not be the best way to go about it," Keith noted.
Jamie then asked Elizabeth a tough question about Amber and Matt's marriage.
"Knowing what you know about Matt and Amber's rocky relationship, do you think Matt has held up his end of his vows -- being respectful, patient and kind?" Jamie asked.
"No! He's definitely not done that!" Elizabeth replied.
"Let me put this kindly: Regardless of the circumstances, you can't wait eight weeks -- eight simple weeks [to] give something a shot and just try it and not hurt someone? I am referring him to staying out [that first] night."
One 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.
"In that moment, like, taking off your wedding ring and then 'allegedly' forgetting to put it back on, you don't forget to put your wedding ring back on! You knew you were doing something," Elizabeth said, seemingly accusing Matt of cheating on Amber with another woman.
"[Even though] it's an experiment... you're committed to someone, regardless of how mad you are or whatever. It didn't even seem like they were mad at each other! You took your wedding ring off and then went out and didn't come home."
Elizabeth concluded, "One plus one equals two. That's not cute. It's not a cute look."
