“She wishes Matt would just move on and leave her alone,” an insider told the site. “Amber gave Matt opportunity after opportunity to make their relationship work, but he just kept messing up. The relationship was toxic — she could never trust him and they were constantly fighting. She finally managed to get the strength to walk away from him for good, but he’s still trying to pull her back in. He’s constantly calling and texting Amber, begging her to give him another chance, but she’s done with him. He had his chance and he blew it.”

As viewers witnessed on the last season of TMOG, Amber discovered that Matt cheated on her after she saw inappropriate Facebook messages between the retired DJ and an unidentified woman from 2016. After taking a break, the Never Too Late author gave Matt a second chance and attempted to fix their relationship while filming WE tv’s Marriage Boot Camp Reality Stars.

However, Amber later confirmed on July 1 that she and Matt were officially dunzo — and revealed that she regretted signing on to the reality series. “I’m doing a show that I should have never agreed to do,” she wrote. “I’ve been taken out of my element to many times, however, I’ve learned a lot.”

While the show couldn’t save her romance with Matt, Amber can thank Marriage Boot Camp for her current relationship with Andrew, who worked as a crew member on the show. “It makes sense Amber and Andrew grew close during filming,” a source previously told E! News. “Her relationship with Matt was in bad shape and when you’re shooting a show like this where there is a lot of heightened emotion, participants bond with the crew.”
