Ever since Teen Mom 2 fans learned that Kailyn Lowry and Javi Marroquin are getting divorced, speculation about what caused the split has been running rampant.

We may never know exactly why Kailyn and Javi to call it quits, but there’s certainly no shortage of theories.

Many fans have been placing the blame squarely on Kailyn’s shoulders, claiming the 24-year-old mother of two became romantically involved with someone else shortly after her husband shipped off to Qatar for a tour of duty with the U.S. Air Force.

The most popular theory seems to be that Kailyn left Javi for their longtime mutual friend Becky Hayter.

Kailyn sort of invited the speculation when she posted a photo of herself kissing Becky, then tweeted about how she doesn’t want to be labeled as gay or straight, and just wants to “love people.”

Now, however, she’s clarifying that she wasn’t romantically interested in anyone when she and Javi made the decision to go their separate ways.

“I didn’t leave Javi for anyone though,” Kailyn tweeted earlier this week.

Indeed, scenes from recent episodes of Teen Mom 2 that capture the couple’s tense final weeks together do make it seem as though infidelity (at least on Kailyn’s part) was one of the few problems they weren’t dealing with:

And given the recently-confirmed fact that Kailyn and Javi have been separated since December means that she and Hayter would’ve had plenty of time to form a relationship, even if they didn’t begin dating until after her split from Marroquin.

Again, we may never know exactly why Kailyn and Javi chose to end their marriage.

Or she may reveal all in the upcoming season 7 reunion special.

Whatever the case, Kailyn isn’t a compulsive liar like some of her co-stars (Looking at you, Jenelle!) so we tend to believe her on this sort of thing.
