Things seemed to be going well for former Teen Mom 2 couple Kailyn Lowry and Javi Marroquin, but that appears to have changed, as the United States Air Force member filed for child support over their three-year-old son, Lincoln. The revelation was made on Monday night’s new episode of the reality series — which the blonde beauty referred to as “a slap in the face.” Watch the video for more on this!

Kailyn and Javi were married for four years and announced in May 2016 that they would separate. Their divorce was finalized in December, and Kailyn briefly moved on from the relationship with Chris Lopez, the father of her third baby, while Javi has also dated a number of women — including Cassie Bucka, Madison Walls, and Lauren Comeau. Both parties accused each other of cheating during their time together, though Kail also detailed in her memoir, Hustle & Heart, that his jealous and controlling nature led to the demise of their relationship.

Kail also shares a seven-year-old son, Isaac, with her ex-boyfriend Jo Rivera. Before baby No. 3 was born, it was rumored she would raise the baby — a boy who has yet to be named — as a single mother. It appears as though Chris has stepped up to the plate since their newborn’s arrival, though a previous report suggested he could complicate their situation by filing for custody.

“Chris has no desire to try and take his kid away from Kailyn, but his mom is concerned about visitation rights,” a source told Hollywood Life. “She truly thinks he would never take things to that level, but just the threat of losing her baby is enough to send her into a tailspin right now. Kailyn still has a lot of pregnancy hormones surging through her body. She’s feeling very emotional and vulnerable, plus she’s looking after a newborn as well as two other kids, so she’s exhausted and sleep deprived. Kailyn’s an awesome mom though; she’s proved that. And although she hasn’t got her parents in her life, she does have a strong support network around her.”
