In an exclusive sneak peek at Friday's Marriage Boot Camp: Reality Stars, the couple heads into the final ring ceremony where they will have to decide to recommit or separate.
"You can cut the tension with a knife because my life could change in a minute," Sugar Bear, 43, says prior to the ceremony.
There's definitely reason to worry. It seems as though Shannon, 36, is on the fence about taking him because she's "scared to get hurt again."

Earlier this season, Sugar Bear admitted to his wife that he had "experimented with guys", something Shannon long suspected after finding more-than-friendly texts with men and women on his phone. Thompson also cheated with a coworker's wife.
At the final ring ceremony, he admits, "I know I've hurt you and the girls, and I want to start over fresh. I love you, but you could love me a little bit back? Not much. Just a little bit."
"I think that you've made huge progress here," she responds, "but you've made bad choices. I believe you want to change, but I don't know if you can change."
Marriage Boot Camp: Reality Stars' season finale airs Friday at 9 p.m. ET on WEtv.
