Days after the Teen Mom 2 star and her husband, Jeremy Calvert, celebrated their third wedding anniversary apart, Messer has taken to Twitter, where she's seemingly confirmed someone has been lying to her.

"You should never have to lie to please your loved ones and tell them what they want to hear," she wrote on Twitter Monday night. "This is sad world these days."

Messer and Calvert's marriage was first reported to be on the rocks in October of last year, when Calvert claimed she cheated on him with her ex-boyfriend Robbie Kidd. Although the reality couple reunited on New Year's Eve, their relationship has appeared strained ever since.

Then, on Monday, The Ashley's Reality Roundup reported that Calvert has been seeing another woman behind his wife's back. Although no details about the woman were given, the site revealed Calvert is now living like a "single man," and plans to tell his side of the Messer cheating story during the upcoming season of Teen Mom 2.

Over the weekend, Messer confirmed she and Calvert spent Easter apart.

“This isn’t the only holiday I have spent without my significant other,” she wrote. “Some days are harder than most. I have remained strong through it though and my strength has seen me through…Just as it does today and many more struggles to come!"

Messer will return to MTV later this year in Teen Mom 2 season 6, which is currently in production.
