Kailyn Lowry and Javi Marroquin </a>had a lot of fighting left in their failed marriage!<br /><br />In a sneak peek clip for Marriage Boot Camp, the Teen Mom 2 stars hashed it out during a workshop that included heavy balls that represented the issues in their relationship and they had to throw them back and forth until someone took the blame for the problem.<br /><br />One problem, “insecurity,” Kail said as she passed it to her ex-husband. She said, “I feel smothered by your insecurities. You make something out of nothing and then you never let it go. Ever.”<br /><br />Javi tossed, “infidelity" to his ex-wife. He said, "When you have to sleep with your phone under your pillow because you’re scared of what I’m going to see. I don’t agree with that.”<br /><br />Watch the clip above! Marriage Boot Camp airs Friday nights at 9pm ET, only on WE TV!
