A Timeline of Nikki Bella and John Cena's Rollercoaster Relationship

The WWE star confronts some uncomfortable feelings about her fiance.

The closer Nikki Bella gets to her and John Cena's wedding date, the more "deep feelings" about her relationship are starting to surface.

While arriving at her Parisian bachelorette getaway with her pals, Nikki voices concerns about John and their conflicting schedules, in a preview for this Sunday's episode of "Total Bellas."

"This past week he just thought, because he had the week off in San Diego, I was gonna take a week off," Nikki says to her friend, "I'm like busier than ever. So he's like, 'I was really lonely.' I saw him every morning and every evening. Emails don't end just because you want my time. It's really tough."

"It's funny because, the closer and closer I'm getting to the wedding, the more of these deep feelings that I've had over the past six years just are coming to the surface," she adds in a confessional.

Nikki tells her friend that she feels very "connected" to Paris, John doesn't really enjoy traveling unless it's for work purposes.

"That's why it's good you had a few days here, even by yourself, just to like rest and do exactly what you want to do," her friend says to her.

Although the show is a few months behind, we know that Nikki and John never got married. From the slippery slope that Nikki seems to be on, we can't say that we're surprised. However, the reality star recently updated her followers in a YouTube vlog last week in which she said that they are currently "just friends."

"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 began 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."

"We are both working on each other, and trying to work on us," she continued. "We talk every day. He is not only my best friend but he truly is one of the most amazing people I have ever met. He has patience with me and he has really taught me a lot over the past few months. I think one of those things is an inner strength I thought I had but I didn't realize how strong I had it."

We will have to see how it all goes down in the two-hour "Total Bellas" bachelorette party special Sunday at 9 p.m. EST on E!
