Kailyn Lowry is allegedly hoping to win her ex-husband back as she prepares to welcome her third child as a single mom.

Just over one year after the Teen Mom 2 star announced that her three-year marriage to Javi Marroquin had come to an end, an insider claims the reality star is loney and freaked out about becoming a single mother of three young children.

“Kailyn [Lowry] is so lonely right now. She’s scared about the future and really freaked out about raising a third child on her own," a source told Hollywood Life on July 25. "She has started seriously missing Javi [Marroquin], and desperately wants to get back together with him. Javi’s moved on though and has no intention of returning to Kailyn and all her drama. He’s really happy now and as far as Javi’s concerned, he and Kailyn gave it a shot before and it failed miserably, so it’s not going to work again now, no matter how hard they try."

As fans may have seen, Marroquin recently went public with her new girlfriend, Lauren Comeau, and spent this past weekend with her in South Carolina, where she resides.

"Nobody thinks Kailyn’s still genuinely in love with Javi though, as much as she kids herself she is, it’s way more about wanting to feel secure and having someone there by her side, and that’s not a strong enough foundation to build a relationship on," the source added.
