We can hardly keep up with Kailyn Lowry and Javi Marroquin's relationship.

On Monday night's new episode of Teen Mom 2, it appeared the couple could get back together — despite having nasty, public spats with each other since announcing their divorce in May.

Kail was unhappy to learn that Javi, a member of the United States Air Force, made out with another woman while she was away in Hawaii, even though they are no longer together. She kept teasing that there was a chance they could reconcile, as she came back from her trip with a clear head and fresh perspective.

Javi, who is the father of the blonde's three-year-old son, Lincoln, also admitted to producers that his ex cried upon seeing him when she got home — which she denied.

Both parties accused each other of cheating during their relationship, which we've seen play out on the MTV reality series. However, Kailyn also admitted in her latest book, Hustle & Heart, that Javi's jealous and controlling nature were also factors that led to the demise of their marriage.

"When he did things like demanding that I unlock my phone to prove I had nothing to hide, or calling me constantly when I was enjoying time with friends to make sure I wasn’t doing anything ‘sneaky’ behind his back, it became clearer and clearer how little my husband trusted me,” she recalled. “I had done nothing to make him doubt me. I never lied, never went behind his back and I was never unfaithful. For some reason, he was convinced otherwise.”

Just last week, Kailyn and Javi got into a Twitter spat over why they ended things. Their divorce was made final in December after four years of marriage.

"I thought we divorced because she didn't want more kids? That's weird," he said at the time.

Kail fired back with, “You blamed me for miscarrying and our marriage was toxic, why would I want more kids with you?”

We bet this drama is far from over!
