Nikki Bella Is 'Exhausted And Done' With John Cena, Says Relationship Has Come To An 'End'

The Season 3 finale of the reality series could not come at a better time as fans are most surely reaching both their wits end and the limits of their prodigious patience. Thankfully, it seems we are finally getting some closure come Sunday.

They were going to get married. Then the wedding was called off. Then they got back together after a change of heart and the wedding was back on again. And now they are breaking up (again) for good this time -- at least it seems that way. (Are you still following this?)

In a preview clip for Sunday's finale the Bella twins discuss the current state of affairs. Nikki was given an ultimatum by Cena regarding their impending (second) wedding date and whether or not they'll even stay together. The "pressure" as she put it did not help things.

Brie performed an emotional check-in with her sister after Nikki stayed alone in Cena's house while he was away on business, "So how was last night?"

"It was very, very hard," Nikki replied. "Taking a shower and seeing like his razor. His suits and everything. Just sucks."

"I wish it could be different," she continued, "and that's why I've had almost six years of working on us and fighting. And I've just hit the point where I am just so exhausted and done."

"So he's waiting for my final decision," Nikki said, tears welling up in her eyes. "Which I think I know it. I'm just afraid to say it."

Brie asked, "Why are you afraid to say it?"

"Because I just don't want to hurt him," Nikki said breaking down in tears. "It's just hard when you love someone so much and care for them so much but you just can't do it anymore. It's not his fault. It's not my fault. You know we've had this amazing love story. It's just come to an end."

So that should be it right? Probably not if "Total Bellas" comes back for a fourth season - - judging by how the show works like an emotional ping pong game that will go on for eternity.

To say that it's been an exhausting season of "Total Bellas" is an understatement. To use the Bella twins favorite term, it's been a "rollercoaster" of emotions.

We know that Nikki doesn't end up walking down that aisle, but for awhile it seemed that there was hope on the horizon for the couple. The reality star recently explained on her YouTube channel that she is "just friends" with Cena at this point -- however, they do speak to each other every day.

"It has been a super emotional roller coaster ride and I think it's hard for people to understand because we film and things get shown a few months after and people are like, 'Are they together? Are they not?'" Nikki said on her vlog. "Because I am a reality star, and I do have a reality show ... I feel like I have to say what's the update on John and I, but right now we're just friends."

"Total Bellas" season finale airs next Sunday at 9/8c on E!, but the drama will continue when "Total Divas" returns September 19 for Season 8. Watch the just-released trailer for that one below!
