Nikki Bella Says John Cena Is 'Pressuring' Her Too Much -- Amid Report She Is Moving Out
A Timeline of Nikki Bella and John Cena's Rollercoaster Relationship

The WWE star contemplates calling off the wedding again.

Things might actually be over for Nikki Bella and John Cena.

A new preview for the "Total Bellas" season finale was released Wednesday hinting at even more trouble in paradise for the couple. The timing of the teaser came just hours after a new report emerged claiming Nikki is moving out of John's house and is in the market to buy her own place.

In the teaser clip for Sunday's episode the professional wrestler indicates she is going to call off their wedding once again amid ongoing problems in her relationship with John. Earlier on Wednesday TMZ reported that Nikki was looking for a house in San Diego -- she had been living at John's place in the area, despite the breakup, while he has been traveling in China.

The timing of her house hunt and the teaser for the reality show all seem to point in one heartbreaking direction: the couple may finally be over for good.

In the preview Nikki expresses her ongoing epiphany that "something" is holding her back from walking down the aisle. During an emotional car ride, the reality star breaks the news to her sister, Brie Bella and her mother, Kathy Colace.

"There's something that is making me not like feel like I can't walk down that aisle right now," Nikki says in the clip. "And that doesn't mean ever with him. I just can't do it right now."

Nikki explains how it's "tough" as the "tables have turned," as John will do "anything" to work on their relationship and is "fighting really hard" for her. Nikki recalls that she told John that at the moment she needs to work on herself and says she has packed herself out of John's house.

"I was at the point like if I don't pack up and leave now -- I know my personality -- I'm just gonna again put myself on the back burner so I legit have not slept, I packed until 4 in the morning," she explains.

Nikki adds that she didn't give herself enough time when they first called it off, because she was so excited that John changed his mind about having kids.

"I couldn't believe it," she says, beginning to cry. "I never thought I'd hear that, but I realized that there was such a deeper problem."

"Do you see yourself getting back with him?" Brie asks.

"He wants me to take the day to really think about it," Nikki replies. "But to have a healthy, happy lifetime with him, I have to take a while myself."

Nikki explains that she feels the pressure, as everything is a "time limit."

"John, when I left, he wanted me to give him a few days to make my decision," she laments in a confessional. "This has been my issue the whole time, it's that pressure thing. Everything is a time limit."

"Like you have to get married this point and you have to do this," she adds. "Nothing can just be. So it's like even when he gives me this time limit if like to make decision if I'll get married or not it's just like I can't even tell you that you can't put a time limit on it. You just can't."

To say that it's been an insane season of "Total Bellas" is an understatement. To use the Bella twins favorite term, it's been a "rollercoaster" of emotions, specifically for John and Nikki's relationship.

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 her and John were "just friends," but that they spoke 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!
