Catelynn Lowell and Tyler Baltierra have been together for a long time.
A really, really, really long time.
Forget being high school sweethearts -- they're actually middle school sweethearts, if you can believe it!
They got together when they were just twelve years old because, as Tyler explained in that book they released a few years back, Catelynn had "the biggest tits in seventh grade."
But it doesn't matter why they got together, because they've obviously formed a deep, loving relationship.
They've been through so much together, including but certainly not limited to the abusive, drug-fueled marriage of his father and her mother and the birth of Carly, the child they placed for adoption.
Things were rocky between them for a while during those teenage years, but they stayed together and now they're married with a daughter, Nova, and they've been open about their plans to expand their family.
Unfortunately, it looks like they've entered a bit of a rough patch in the last few months.
Catelynn had a miscarriage back in the fall, and both she and Tyler had a hard time dealing with it, understandably.
She struggled so much that she contemplated suicide, and when she realized how bad things were, she decided to spend six weeks in a treatment center in Arizona.
Tyler was very supportive of that, but when she decided to go back for another six weeks shortly after coming home ... well, that was a bit different.
All of this went down on the last Teen Mom OG season finale -- about three weeks after coming back, Catelynn told Tyler that she was still struggling and thought another rehab stay would be the best thing for her.
He urged her to try dealing with things at home first, since Nova had a hard time going without her mom for so long during her first trip to rehab.
But she'd already made up her mind.
In a surprisingly candid chat with his sister, Tyler complained about Cate's decision, and he even compared her leaving for multiple trips to rehab to his father being in and out of his life when he was a child.
He said that he'd told Catelynn that going back to Arizona might be the best thing for her, but that trying treatment at home would be the best thing for their daughter.
Her response to that, according to Tyler?
He honestly seemed a little disgusted by her attitude about Nova's wellbeing, and many fans were as well.
He was so upset that during that conversation, he even told his sister that maybe he and Catelynn weren't right for each other anymore.
It was the second reference to a possible divorce in that single episode -- earlier. she'd told him that maybe he should just leave her, since she'd been having so many problems.
Not a great sign, honestly.
But the episode aired, and Catelynn and Tyler tried their best to prove that these days, they were doing a lot better.
There have still been some pretty concerning signs though.
One was a tweet Tyler wrote last month in which he wrote that even though he was lying in bed next to his wife and listening to his daughter sleeping on the baby monitor, he still felt "so empty and so alone."
Another has been the poetry he's been sharing on social media, which is all pretty dark and has honestly made it seem like he could perhaps be suicidal.
But a couple of days ago, he shared a new poem ... and if we were Catelynn, we'd definitely be feeling a little upset.
In this poem, Tyler called himself "that pathetic f-ck up who got famous just for f-ckin his girlfriend & gettin her knocked up."
"That motherf-cker ain't sh-t," he continued, "that motherf-cker's gotta take a hint, he's gotta get it together if he wants his life to fit."
"That motherf-cker's gotta get a job even though I doubt that he could, & he's gotta leave that broad if he ever wants to be heard."
So ... that's not great.
In the caption for this post, he explained that these were the kinds of things he hears from people -- from his haters, if you will.
It sounds like he doesn't actually believe these things, he's just turning insults around because he thinks it's "ironically motivating."
Still, if you take this and add in the other developments from the past week, things aren't looking too great for the Baltierras.
As you may have heard, there was a big fuss because fans noticed that on Catelynn's Instagram, she lists her last name as Lowell instead of Baltierra, her married name.
The thing is that her name has always been Catelynn Lowell on Instagram, and the name thing got more attention than a much more interesting little tidbit, which was that for a little while, she actually unfollowed Tyler.
Besides that, they didn't spend Mother's Day together -- she was in Florida and he was in Texas.
He didn't even write a big gushy message about her for the holiday, which, if you've followed this couple for any length of time, you know is very, very strange.
There's been so much going on to point to a possible split that Catelynn felt the need to address the rumors.
In a statement, she wrote that they aren't getting a divorce, and that "couples go through ups and downs, that's normal life."
"We are a solid couple that will work through anything life throws at us!"
Which is even more suspicious, because while she did say they aren't getting a divorce, she definitely implied they were going through some issues.
Come on, Baltierras, pull through!
