"Teen Mom 2" stars are being plagued by relationship issues. The recently arrested Jenelle Evans has learned that Nathan Griffith cheated on her through Ashley Madison, while Leah Messer, who is suffering from substance abuse, now wants second ex-husband Jeremy Calvert back. Looks like the problems of the two moms are piling up.

Jenelle may now be contemplating on either thanking or denouncing Ashley Madison now that she has learned that ex-fiancé Nathan Griffith was never loyal to her the entire time they were together.

In the wake of the Ashley Madison hack, Griffith's email address surfaced, revealing that he may have shared illicit relationships with other girls. Nathan has yet to answer the issue that is also being faced by "19 Kids and Counting" star Josh Duggar and "Real Housewives" star Josh Taekman. However, Jenelle was more than willing to give her two cents on the issue.

Radar Online has learned that Evans was far from devastated upon hearing the news. She even admitted that she was not surprised about Nathan's Ashley Madison account since for her, "Once a cheater, always a cheater."

She also said that if anything this is an embarrassment to her ex and to his family and friends. "I think he embarrasses himself and whoever [is] associated with him — especially the girl he's with now, because supposedly she doesn't believe in sex before marriage. But Nathan does," she was quoted as saying by the publication.

Despite saying that the issue does not embarrass her, it appears that the "Teen Mom 2" star still feels sad over her breakup with Griffith. A couple of days ago, Jenelle took to Instagram a photo of the shoes she was supposed to wear on their wedding day, Perez Hilton reported. She captioned the snap "Never got to wear these.... One day."

The post comes days after she assaulted Griffith's new girlfriend whom Evans claims to be someone who "doesn't believe in sex before marriage."

Meanwhile, another "Teen Mom 2" star is facing some relationship problems, and it is no other than Leah Messer. She was recently confronted by ex Corey Simmons about her substance abuse, now she's bound to confront her own feelings for second ex-husband Jeremy Calvert.

According to Design&Trend, although Leah took it to herself to complete a rehab stint, Jeremy is still not pleased and is perfectly fine post-divorce. In a sneak peek, Leah tells her stylist, "Jeremy left his ring and a fraud sheet of a divorce paper. I just never want to give up on him. What if I keep believing in him and it eventually like clicks."

Only time can tell if Jeremy also wants Leah, who has been struggling with alcohol and narcotics abuse. Nevertheless, it's good that she's been positive throughout this ordeal. She even posted an uplifting Facebook post which read: "God, grant me the serenity to accept the things I cannot change, the courage to change what I can, and the wisdom to know the difference," as quoted by InTouchWeekly.

"Teen Mom 2" is set to air a new episode this Thursday night at 10 p.m. on MTV.
