The relationship between Kailyn Lowry and Javi Marroquin ... well, it hasn't been great for a very, very long time.
We might go so far as to say that it's never been all that stellar.
They got married when Kailyn was just 20 years old, and Javi is a year younger than her. It wasn't long after that that they welcomed their son, Lincoln.
And before they were even married, we saw them get into some pretty terrible fights.
Then, of course, there was all the divorce drama -- we're still not sure exactly what happened there.
Javi says Kailyn cheated, she says that it was technically cheating because they were already separated, he says that doesn't count as an excuse because he didn't know they were separated.
He's broken into her home, she's filed a protective order against him because she said she feared for her safety.
It's a lot.
But, as we saw in a heartbreaking little scene on Marriage Boot Camp last night, there's still at least a little bit of love between these two.
This new episode was the one where the couples play pretend that one of them is on life support, near death, and the other has to, you know, deal with that.
This time around, Kailyn is told that Javi was in a bad car crash and he's now brain-dead, and so she has to say her goodbyes.
And while she's normally known for being cold and unemotional, her reaction to the exercise was pretty intense.
"This is f-cked up," she says upon seeing Javi in a hospital bed. "No, get me out of here."
She starts crying, something we rarely see her do, and she tries to leave, but the therapist pulls her back in the room.
She's asked what she wants to say to him -- her pretend last words to him -- and she says through tears "I'm sorry, and I'll take care of our son."
The therapist then pulls out a letter Kailyn had written to Javi earlier in the season -- one that she thought was going to be destroyed.
"I have said the things I wrote in the letter a million times," she admits in a later interview, but "it wasn't appropriate in the time and place."
So since she refused to read the letter, the therapist read it for her.
"I would never want my sons to grow up to be like you are right now," she had written to Javi. "You've acted childish and don't know how to control your feelings."
If you want to creep a little, you can pause the video and read the rest of the letter -- it's all about how Kailyn doesn't want her boys to "think it's OK to try to control someone else" or make them "feel unsafe in their own home."
When asked what she'd like to say to Javi on his deathbed, she starts crying again and says "I care about you so much, and I never knocked you as a father, and I'll make sure that our son is taken care of."
Pretty heavy stuff, right?
Later, Javi admits that he never thought she'd actually cry during the exercise.
"It was nice to finally get some kind of emotion out of her," he says, then to Kailyn herself, he complains "You never tell me how you feel."
"If you were to die, a part of me would die. You will always have a piece of my heart."
Is there hope for Kavi yet?!
No, like we know they're divorced now and she's had a baby with another man since this was filmed, but still ... do they have a chance?
