Jeremy Calvert has filed for divorce from “Teen Mom 2” star Leah Messer, In Touch Weekly exclusively reported Tuesday. The couple has been married for two years, but recently began to display signs of trouble after Calvert accused his wife of cheating with former lover Robbie Kidd, the same person she slept with the night before she married first husband Corey Simms.

“She always thought she’d be able to win [Jeremy] back,” a source told the celebrity site. “The fact that she can’t has made her a total mess. She’s hit rock bottom.”

“They’ve been having problems for a while now, and Leah cheating in October was the final straw,” the person added. Messer denies any wrongdoing publicly, but she’s apparently “begging” for her husband’s forgiveness. “But he’s totally done with her,” a source said.

But Leah’s still not willing to give up. Even though her marriage with husband No. 2 is apparently on the fritz, or even over, Messer supposedly quit the reality show that made her famous to try to salvage her relationship.

“All the attention from the show played a hand in one failed marriage, and she’s not going to let that happen again,” a source told Radar Online. “Leah is doing everything she can to keep her family together, including leaving reality TV.” The insider added: “Things are still rocky for them.”

Jeremy Calvert has expressed frustration with his marriage on social media in the past, but there still might be hope. “She says they’re having a difficult time but haven’t given up yet,” a source told Radar Online. He accused Messer of cheating on him weeks ago, then Monday he simply tweeted, “Done,” which had many believe he was referring to his marriage with the “Teen Mom 2” star.

The two are having a “difficult time” but are not going to give up just yet, an insider told the news site. Calvert has written about his RV, his “home away from home,” and said he was tired of keeping his "mouth shut.”

He has begun to follow several different women on Twitter, Radar wrote in a different story. He was reportedly seen flirting with a bartender while Messer was at home.

The reality star has presented a different façade on social media recently. She’s shared messages from fans that tweet about her being a good mother with a warm heart and last posted something that would make it seem like she and Calvert were working things out. “You don't have to keep me falling like this, but it'd sure be cool if you did,” she said.
