Kailyn Lowry and Javi Marroquin's marriage seems to be getting worse with each episode of Teen Mom 2.

Insider Defends Kailyn Lowry's Trip To Los Angeles

In a sneak peek at Thursday night's new episode of season six, Lowry and Marroquin are once again at odds, this time over her friend Sterling, who has caused them tension during a trip to Orlando, Fla.

"I planned this whole day for you and now you're in a bad mood and you're not going to enjoy it, so then I'm not going to enjoy it," Marroquin tells Lowry in a sneak peek of the new episode. "I guess we'll go home because once again, your friends come first."

Lowry wants to spend time with Sterling, but after she voiced her concerns for the couple's marriage, Marroquin has begun feeling uncomfortable around her. So, instead of simply welcoming her to their activities in Orlanda, Lowry asked Marroquin if he was okay with it. When he couldn't tell her he was, all hell broke loose, and moments later, Marroquin hit a piece of wood in the road, leading to a flat tire.

"I can't even see the f**king wood that's f**king in the middle of the road, man," Marroquin fumes.

"Don't blame me!" Lowry responds.
