Let no one ever say that divorce has to be messy.

Or ugly.

Or really disagreeable at all.

Don't believe us? Just ask Amy Roloff and Matt Roloff.

Not only did these two split after nearly 27 years of marriage and four kids, but they continued to work together on the TLC reality show Little People, Big World.

Moreover, they actually continued to live on the same property until very recently, residing just 100 yards or so away from each other on their mutually-owned farm in Oregon.

Just how well do these exes get along? Consider the following:

Amy just got engaged last week to boyfriend Chris Marek -- and Matt has now become the first family member to congratulate her in public!

The Roloff patriarch did so in sort of a subtle way, but he definitely did so nonethless.

"My buddy Ty and I got together for our regular Saturday morning breakfast today,” Matt as a caption to a photo he shared of himself and his friend over the weekend, adding simply:

“He doesn’t do social media … so I filled him in on Amy’s exciting engagement news. Congratulations to Amy and Chris!!"

There you have it, folks.

We have no doubt that Amy's kids, all of whom welcomed Marek into their lives years ago, are thrilled for their mother.

But, as far as we know, none of them have said anything about the engagement on social media just yet.

Marek popped the question a few days ago, shortly after Amy turned 55 years old.

“I’m excited, I’m so surprised, I’m thrilled!” Amy told People Magazine of the engagement, adding to the publication:

“I never in a million years thought I’d be getting married again, but I also hoped for it! Now that it’s happening, I couldn’t be happier or more excited.”

She and Chris have been dating for almost three years and fans around the globe had been hoping/anticipating an engagement announcement could be forthcoming.

Even Marek, who has rarely spoken to the press during his courtship of Roloff, commented on the major development after Amy agreed to marry him.

“I was very nervous! It had to be a heart shaped diamond because I knew that’s what Amy wanted," he said.

Amy has since shown off her engagement ring (it's gorgeous!!!!!) on Instagram and included with the snapshot a caption that reads:

I was so surprised when Chris asked me to marry him. I said YES. I couldn’t be happier and so looking forward to this new part of our life journey together. I’m blessed.

Love you Chris. I love us.

No word yet on a wedding date or location or anything.

But the couple has plenty of time.

As for Amy and Matt?

They've been nothing but respectful of each other over the years, with the notable exception of Amy having come out with a very personal memoir this summer.

In one section, she writes in detail about her split from Matt and states firmly that he cheated on her back in the day with his current girlfriend, Caryn Chandler.

In an emotional sense, at the very least.

“We had someone that worked for us for a very long time, on our farm,” Amy writes of Chandler in the book, adding:

“And I believe - this is all from my perspective - that there was more than just friends going on. And I think that evolved to a point where that got in the way of our marriage as well."

Yikes.

And yet: isn't it nice to see Matt send Amy his best wishes, even in the wake of this controversial release and revelation?
