Amy Betrayed! Matt Roloff Treating Girlfriend Better Than Ex-Wife During Marriage

Little People, Big World matriarch Amy Roloff is not over her divorce! An insider exclusively revealed to RadarOnline.com that Amy feels betrayed by her ex-husband Matt one year after finalizing their split.

As RadarOnline.com readers know, Matt, 56, revealed he is dating longtime assistant Caryn Chandler only months after they announced their divorce following 27 years of marriage.

Chandler, 49, had been working on the family farm since 2006. While Matt and Amy were still married, Chandler even made appearances on the the show.

"Of course Amy feels betrayed," the insider told RadarOnline.com. "The way he's treating Caryn is nothing like how he treated her during their marriage. It was like a blow to the chest."

The source close to Amy added, "It really made Amy feel insecure about who she was and the type of wife she was."

On last week's episode, Amy, 53, opened up about how hard it was having to invite Chandler to family events — most recently, Audrey Roloff's baby gender reveal party.

"It is hard for me to say 'go ahead and invite Caryn' because it is someone that I've known for a long time," Amy admitted. "Matt's worked with her for many many years. So that will always hurt to some degree. But it is something that I will have to be an adult about — doesn't mean I have to accept it."

Despite her feelings, Amy has been dating Oregon-based photographer turned real-estate agent Chris Marek for over year.

"The good thing to come out this though is Chris," the insider added. "She met Chris, and he is so good to her and they are happy. He doesn't take her for granted."

Most recently, the two took a luxurious cruise to the caribbean to celebrate their love.
