by at .  Updated at .

These are very tough times for Teen Mom OG fan favorite Mackenzie McKee. In so many different and tragic ways.

Fans recall that last December, Mackenzie lost her mother, Angie Douthit, following a lengthy battle with cancer.

Around that time, the mother of three was trying to repair her strained relationship with her husband, Josh McKee.

Josh had been caught cheating on Mackenzie several months before her mother's passing, leading to a temporary split.

Now, it looks as though the split may be permanent, as she's threatened before but never quite followed through with.

Why? Well, Mackenzie says she caught Josh sleeping around again, this time with one of her own family members.

Crazy, right? And we know this because shockingly, Mackenzie has decided to air all of her dirty laundry in public.

Take a look ... and fasten your seatbelts:

[UPDATE: Mackenzie has made some additional comments in order to clarify her initial remarks -- and it sounds as though she may be experiencing some major regret.]

1. Calling It Quits

After appearing on 16 & Pregnant and later Teen Mom 3 in its inaugural (and only) season, Mackenzie McKee got married in 2013. Now she says her marriage to Josh McKee, the father of her children, is officially over. And for real this time.

2. Busted!

McKee has never been shy about taking to social media, whether it's sharing her emotions about her mother's courageous cancer fight, or fighting battles with her estranged partner. Like clockwork, she took to Facebook today to reveal, in no uncertain terms, that she caught Josh having an affair with her cousin.

3. Letting It All Out

Letting It All Out
Mackenzie, who is only 25 years old, has been through enough drama for a woman twice her age, capped with this latest insanity. She absolutely destroyed her cheating soon-to-be-ex-husband with a lengthy Facebook post that reads as follows:

"I know many have it worse than me. This isn't a pity party. Life has thrown me some huge curve balls. Idk how I've made it here."

7. A Memorable Farewell

“She was so happy for him and her last words to him were ‘I’m so proud of you, pray for me.’” Rest in peace, Angie. One can only imagine what she would think if she were here to read what her daughter has to say about the situation now.

She doesn't know the details, or she isn't sharing them all with us now. Perhaps that's a story for another time.

26. UPDATE: Admitting Fault

UPDATE: Admitting Fault
In a recent interview with Champion Daily, Mackenzie admitted that she might have talked a bit too much trash about Josh. "Was it petty of me to run off of my emotions and type that Facebook status? Yes. Is there always another side of the story. ALWAYS,” she said. And that wasn't the end of her confession:

27. A Nuanced Take

"We both made several mistakes throughout the years I’m not claiming to have been perfect. But one thing we can all see is that he has sucked life out of me.”

28. YES, Hard Feelings

YES, Hard Feelings
“If you ask him, he says I pushed him away,” she went on. “And my side of this all is I never felt valued or loved. Out of everything I have accomplished he was never proud of me.”

29. A Deep Divide

“It didn’t make things easy that he wants out of the spotlight and I run my entire life/income on social media sharing anything and everything which could have done damage on this marriage," she added.

30. Mixed Feelings

Sharing what it was like for her to mourn her mom, McKee went on to explain that “I would tell him daily he is no good and disgusted me, but on the inside it was me screaming for him to just hold me together."

31. A Confusing Situation

A Confusing Situation
From there, Mackenzie painted a bleak portrait of her married life. "Two times this year I have kicked him out of the house just to try to find my sanity. Was it wrong? Sure, I’ll admit that," she said. "But lately our relationship has literally been sleeping under the same roof and loving our kids. He says to me all the time ‘I’m just here until you find someone and I will leave,’ so we both know it was coming to an end but being together for 11 years it was just so hard.”

32. The Ashley Situation

The Ashley Situation
“Long story short I pulled his phone records and found he had been texting and calling a number more than necessary," McKee continued. "And it was my cousin. My heart sank more than ever and that’s when I chose that we were done for good and posted the status.”

33. Come Again?

Interestingly, she later clarified that she had not explicitly accused Josh of being unfaithful to her.

34. Words Matter

On Monday night, Mackenzie addressed things once again on Twitter, where she wrote "I never used the word 'banging' or 'cheating.'"

35. A Little Backpedaling?

A Little Backpedaling?
"Please stop stalking and digging for relatives and invading privacy," she went on. "Josh was texting and calling her for advice on how to handle me and to me that was wrong on both ends and enough to walk away. Now let’s all move along."

36. Back and Forth

Back and Forth
When a fan pointed out that Mackenzie did accuse Josh and Ashley of having an affair, Mack fired back: "They refuse to call it that. But I do think an emotional affair is a thing. I do not go to men for marital advice. Unless a counselor."
