'Teen Mom 2' Leah Messer Attempts To Reconcile With Jeremy Calvert While Dating T.R. Dues [Report]

Leah Messer may have fallen back into old habits. Amid her months-long relationship with T.R. Dues, the Teen Mom 2 star has been accused of texting her ex-husband, Jeremy Calvert, even going as far as to tell him she loves him. Understandably, her boyfriend is not happy.

Last month, "T.R. looked in [Leah Messer]'s phone, and saw she had written 'I love you' to Jeremy, and even called him 'babe,'" a source close to Dues told Radar Online on January 18. "He was furious!"

And while Leah Messer and Dues are currently living together in West Virginia, the 32-year-old personal trainer, whom Leah Messer first began mentioning on Twitter in early 2015, is thinking about moving out.

"He wants to get his own apartment, just in case things go south," the insider alleged. "Friends are warning him that [Leah Messer] cheated on her exes, and is likely to do it to him, too."

As fans of Teen Mom 2 will likely recall, Leah Messer admitted to cheating on her first husband, Corey Simms, just days before they got married, and she was also accused of cheating on her second husband, Calvert not once, but twice. Following Calvert's Twitter allegations in October 2014, which claimed he had caught Leah Messer cheating on him with Robbie Kidd, the same man she slept with prior to her marriage to Simms, Leah Messer appeared on the Teen Mom 2 Season 6 reunion show, where it was confirmed that she had cheated on Calvert with Simms sometime after he married his second wife, Miranda, in June 2013.

At just 23-years-old, Leah Messer is twice divorced and has three children, two of whom she recently lost primary custody. However, later this month, as Radar Online recently reported, she and Simms will return to court in West Virginia, where she hopes to regain custody of her 6-year-old twins, Ali and Aleeah. Unfortunately, her first husband doesn't think she has a chance.

"Corey thinks the judge will keep the arrangement the same," a family insider told the site. "[Leah Messer] hasn't made any changes, so there's no reason to reverse the order."

Meanwhile, Leah Messer feels she has proven herself to be a good parent.

"She's optimistic," a source said. "[Leah Messer] knows she deserves to get her girls back."

As she prepares for her upcoming court appearance, Leah Messer, who has battled rumors of a drug problem for nearly two years, is said to be "dedicated" to doing whatever it takes to get her girls back, even if it means staging a breakup from Dues. According to another report, Leah Messer has been telling friends that she split from Dues, but in reality, the two are still living together with his two children, Tyshawn, 8, and Angelo, 4.

"[Leah Messer] knows it doesn't look good for her to have a new man in the house already," an insider told Radar Online, claiming Messer's relationship with Dues actually began two months prior to her divorce from Calvert in June of last year.

Leah Messer also did her best to keep her relationship secret last year as she filmed the sixth season of Teen Mom 2. In fact, despite living with Dues, he was not seen on camera at all or even mentioned until the reunion, when Simms confirmed his daughter had told him about their relationship.

Leah Messer and her family, as well as Simms and Calvert, will be featured during the upcoming seventh season of Teen Mom 2, which is expected to air on MTV later this year.
