A white wedding might be a long, long way off for these two.
After initially calling off their wedding, the couple reconciled after John agreed to have kids with Nikki to keep the love of his life. But that may only be the one of their issues.
"I've been miserable and I've been trying to be happy, but I realize there was just such deeper problem," Nikki cries in a Total Bellas preview for the second half of the season.
"He's wanted a very strong career and he has that," Brie Bella tells her sister. "Unfortunately to have that, he lost the woman of his dreams."
The clip then flashes to Nikki traveling to Paris with her friends and being back back with John. Is even seen Nikki trying on wedding dresses (again!) and all seems to be alright. But, as we all know, nothing is set in stone with these two until they say "I do."
"John and I might be calling off the wedding again," Nikki tells Brie over the phone, before the clip ends in a cliffhanger.
Check out the full teaser below. "Total Bellas" airs Sundays at 9 p.m. on E!
