Leah Messer may have to watch another one of her divorces play out on TV.
The "Teen Mom 2" star and her second husband Jeremy Calvert have struggled to overcome cheating rumors and may not be able to salvage their three-year marriage, according to Us Weekly.
"Jeremy has been telling people for a few weeks now he's going to file for divorce from Leah," a source told Us Weekly. Another insider told the outlet that the 26-year-old pipeline engineer may not take that course of action.
"They're not really fighting so much," the insider said. "It's just a lot of small things that just build up over time, but it does seem like they're breaking up now."
The trouble started when Calvert publicly accused his wife of cheating on him with an ex-boyfriend Robbie Kidd in October, according to Radar Online. Kidd later confirmed the affair. The couple agreed to try and move on, but that has not as easily to Calvert.
"Leah and Jeremy promised each other that they would try to move on, but Jeremy can't seem to get over the past," an insider told In Touch (via Radar Online). "He's constantly accusing Leah of things- usually cheating."
Calvert and Messer share a 2-year-old daughter, Addalynn. The 22-year-old mother also has 5-year-old twin daughters, Ali and Aleeah, with her ex-husband Corey Simms.
Messer reportedly already took the first step toward splitting when she moved out of the couple's Left Hand, West Virginia home and back into her mother Dawn's house with her three children, according to In Touch (via Radar Online).
Calvert and Messer celebrated their third wedding anniversary on April 4. All seemed well between the two according to the status on their Facebook fan page that read, "Today makes 3 years of marriage for Jeremy and I. #ANNIVERSARY," but Messer's personal Twitter feed relayed a different message.
Messer told fans via Twitter last November that she would not return for a sixth season of "Teen Mom 2." Messer felt "scarred" by how her divorce with Simms had played out on the MTV reality show and didn't want to go through that again with Calvert, according to Us Weekly.
She later had a change of heart after reconciling with Calvert and agreed to return to the show.
