'Teen Mom' Stars and Their Kids

"If she trusts him, good for her," says Kail.

Kailyn Lowry just can't shake the drama with Javi Marroquin, even four years after they split.

On Tuesday's new episode of "Teen Mom 2," Lowry explained some of the blowback her comments on last season's "Unseen Moments" reunion special caused with her ex.

In case you missed it, in a hushed conversation between Kail and Leah Messer, Lowry accused Javi of banging on her hotel room door at 6:30 in the morning. What did he want? "He tried to f--k me," she claimed. "It just aired and Javi was pissed, but I stand by what I said," Lowry said on Tuesday, before talking about the situation with Vee, the wife of another ex, Jo Rivera.

"There's a lot of crazy stuff going on. Lauren wanted to call me after that stuff that aired on TV," she explained, referring to Javi's then-girlfriend and mother to one of his kids, Lauren Comeau.

"I think he played it off .... I don't know, I told him I wouldn't talk about it. Again," said Lowry, who was doing just that. "She was going through Javi to have him get me to be okay with calling her and she wanted him to call me in front of her. I was like she should have just approached me, me and her, because she would have been more likely ..."

"To get the answer," said Vee, finishing Lowry's thought.

Kailyn then told Vee that Javi said he was ready to propose to Comeau, despite all the drama. "If she trusts him, good for her," said Lowry. "I don't wish anything bad on them, I really don't. I don't f--k with her but I also don't wish anything bad on them, at all."

When the engagement actually happened, she was a little more flippant about the whole situation. After a producer showed her Javi's post announcing the news, she added, "I already knew it was happening. I didn't know he actually did it, but I knew it was going to happen."

When asked if she was going to congratulate them, she replied, "No. Good luck." Right before she drove off, she shouted out the window, "He's been cheating on you since you were pregnant. Adios!"

Javi and Lauren got engaged in August, but had a big fight in August of this year. While it's unclear exactly what went down, Marroquin eventually posted a lengthy apology online to Comeau. "Lauren, I'm sorry for my mistakes," he wrote. "I'm sorry I broke your heart, I'm sorry I disrespected you. I'm sorry I took you for granted."

To his two sons -- Eli, who he shares with Lauren, and Lincoln, who he shares with Kailyn -- he added, "I failed you as a father and failed at my attempt to show you both what it is to be a man." The status of their relationship now is unknown, as neither has shared any photos of each other on social media.

"Teen Mom 2" airs Tuesdays on MTV.
