"I'm kind of the assistant principal and she's the principal", he says, noting that it's her choice whether they write their own vows and if they have the wedding on television. "It seems like in the end that was still the truth", the source continues.
On 5 May, they were due to walk down the aisle and say their I Dos but Nikki confirmed their split this week.
On Sunday before the breakup news was announced, the WWE star shared a Walt Whitman quote with his social media followers that read, "Keep your face always toward the sunshine-and shadows will fall behind you".
"It wasn't going to be some showy Hollywood, over-the-top glitzy thing", a source told People of the wedding, adding that Bella was excited to celebrate her heritage with those close to her. "While this decision was a hard one, we continue to have a great deal of respect for one another".

President Trump said the strikes were necessary to prevent chemical weapons from being used on innocent Syrians again. Responding to the airstrikes, Putin on Saturday condemned what he called "an attack on Syria".
The professional wrestlers' wedding was set for next month in Mexico, where Bella was excited to celebrate her heritage with family and friends. "We ask that you respect our privacy during this time in our lives", it added.
A trailer for season three of their E! reality show "Total Bellas" also dropped a majorly ominous hint at an eventual split. "I've told you I don't want to get married and I don't want to have kids, and you do want to get married and you do want to have kids", he told Nikki in a 2014 episode of "Total Divas".
"The only thing that's changed [since the proposal] is he'll text me now saying like, 'I'll miss my bride.' So now he's using the term bride and fiancée which I love", she said at the time.
Cena was apparently going into the union with 'gritted teeth'. "I can't give you that". "It was a little alarming to me".
The source suggests Nikki Bella wanted to settle down and have kids, but Cena didn't want to do all of that.
