Cheater, cheater! In an exclusive interview with In Touch, Teen Mom 2 star Kailyn Lowry opened up about how she REALLY felt when her ex-husband of four years, Javi Marroquin, finally came clean about his infidelity on a recent episode of Marriage Boot Camp: Reality Stars. Fans know they joined various other celebrity couples for Season 9 of the We TV series — where Dr. Ish Major and Dr. Venus Nicolino [Dr. V] attempt to help their troubled relationships.

Javi admitted to stepping out on the new mother-of-three during the “lie detector” episode. “I always knew but I really didn’t want it to be confirmed and definitely [not] the way that it was confirmed — hence my initial question on Marriage Boot Camp: Reality Stars,” Kail said via e-mail. That initial question was, “Do you purposely try to prevent me from succeeding?”

In Touch spoke with Kail as she promoted her upcoming book series —featuring her “crazy dogs” — which will include “a separate book for the boys and then a series of children’s books, inspired by our French bulldog that [her and Jo Rivera‘s son] Isaac gets to illustrate — which is super exciting! Our first Frenchie is always getting into trouble so he kind of inspired the series.”

Fans may recall the former MTV couple was set to release a story together called He Said, She Said. Kail recently revealed on Twitter that this was no longer happening. “Javi initially wrote a book on our relationship [and] divorce, and he didn’t didn’t really like the idea of me writing an answer to it so I came up with combining them,” she explained to In Touch. “I actually wrote my ‘she said’ part and it was nothing but negative, so I reached out to Javi and to the publisher and said, ‘I don’t want to publish this. It’s not going to do anything positive for anyone.’ Javi agreed.”

Kailyn and Javi share a four-year-old son, Lincoln, together and she also welcomed her third son, Lux, with her ex-boyfriend Chris Lopez in August. The United States Air Force member moved on from the relationship with their Teen Mom 2 co-star Briana DeJesus.
