Kailyn Lowry's relationship with Chris Lopez has been such a roller coaster ride, hasn't it?
It's honestly been a little exhausting, and we're not even the ones in the relationship.
Of course, there hasn't been an actual relationship for most of the time we've known Chris existed, has there?
From what we've heard, Kailyn met Chris in college, and they were friends for a while before they started hooking up.
And even though Kailyn became pregnant in late 2016, she and Chris never really had any great romance -- she said on Teen Mom 2 that he had another girlfriend at the time.
Also on the show, we watched her struggle quite a bit with how uninvolved Chris seemed to be during the pregnancy.
She'd call him to invite him to appointments, and he wouldn't show, and then when she was on vacation and was hospitalized for possible preeclampsia, he ignored her calls.
But when their son, Lux, was finally born, he did show up at the hospital, and he even took them home from the hospital.
He helped out for a bit, but before too long, he was gone again.
In this season of Teen Mom 2, Kailyn has accused him of being an "Instagram dad" -- of just being around enough for pictures to share on social media so he looks good.
She also dealt with a bit of a custody battle with him over Lux.
It's been very, very messy.
However, there's been some evidence lately that things are actually good between these two now, despite everything.
More than good, even.
Speculation began a few weeks ago when Kailyn was tweeting about Lux's first birthday party -- at one point, she wrote "I was going to have a Coco theme party for Lux but Chris and I decided to change it last minute."
That means they planned their son's birthday party together, and as we saw in the photos she shared, Chris even showed up to the party.
They sure have come a long way, huh?
But of course, attenting their kid's first birthday party together could just be good co-parenting, right?
It doesn't necessarily mean that they're together.
No, some other posts she's made recently do more to prove that.
This week, Kailyn shared a video on Instagram of her oldest son, Isaac, walking into his newly redecorated room, looking all precious and excited.
In her caption, she thanked Chris, which seems weird, right?
Other people thought so, too, and in a Q&A, also on Instagram, one of her followers asked her "Why did Chris help with Isaac's room?"
"I guess the better question is why wouldn't he have helped?" she responded.
... No, the better question is definitely the first one. It doesn't make sense for Chris to work on Isaac's room, Isaac isn't his kid and, unlike Javi Marroquin, he never got that close to her other children.
As far as we can tell, the only reason that Kailyn would just assume Chris would help with things like that would be if they're together again.
And in another answer in a Q&A, she pretty much confirmed it.
This time, someone asked "What's your sex life like?"
"Only if it's w you babyyyyy," she replied.
And she tagged Chris.
How much more proof do we need that Kailyn and Chris are giving things another go?
Looks like she may make things work with her one true love after all!
