Kailyn Lowry's husband Javi Marroquin has made some shocking allegations against the star of MTV's reality TV show Teen Mom 2. In an interview with Radar Online, Marroquin has claimed that his estranged wife was not faithful to him before and during his deployment in Qatar with the US Air Force.

Marroquin admitted that Lowry filed for divorce in December, but they reconciled before he left for Qatar. However, he was unaware of the fact that Lowry had not cancelled the divorce filing.

"When she brought it up later I was like, 'Whoa, I thought you cancelled this,'" said Marroquin. "I didn't even know she still had it going on. Up until the day we left, to my knowledge, we were good… We were going to make it."

Javi also revealed that he was confronted by several of their friends about his estranged wife's behaviour while he was away, including Lowry' ex-friend Christina 'Peach' Pietrobon.

"It's not about what you know, it's what you could prove," he said. "She would openly talk to people she thought were loyal to her, but when they saw what she was doing they brought it to my attention."

According to Marroquin, Lowry went to Los Angeles to shoot a Teen Mom 2 reunion special in April "with someone else". He even found a "lot of stuff" online which alleged that she had been unfaithful to him.

He said, "A lot of stuff was blown under my nose. I was naïve to not believe it, I didn't want to believe it. A lot of things were swept under the rug. When you sign onto a computer it usually says your password so when I go on, your account is usually logged in. So I found out a lot of stuff."

Although Lowry denied everything, he chose to believe his friends over her. "They're the only people I can believe," he said. "They have no reason to lie to me. Her best friends are telling me this kind of stuff. Why would they lie to me? They didn't like what they saw. They didn't like what she was doing." he explained.

Javi said, "She continued to deny things. I continued to find out things and it was too late. I have screen shots, I have texts and I have pictures. They're saved on a lot of different things just in case. When the time is right, what's done in the night will show in the light."

The couple were married for three years and have a son, Lincoln, aged two.
