Nikki and the "Trainwreck" hunk announced they had ended their engagement in April, just weeks before their wedding, but it appeared they were working to rebuild their relationship at the beginning of the summer.
However, now Nikki has revealed she and John haven't spoken to each other recently, and she is focusing on herself.
"He's doing him and I'm doing me," she tells U.S. news show Entertainment Tonight. "I slowly feel like I'm (taking time for myself). I think it's happiness, and just fully being happy and that's what I want."
However, Nikki admits she is finding her period of self discovery "scary."
"I just feel like I'm at that age where I'm discovering who I really am and what I want out of life and just, like, independence," she adds. "It is scary and you do have these moments of like, 'What am I doing?' - and fear. I just kind of am liking the challenge (sic)."
Nikki, who insists she is not ready to date again yet, and John began seeing each other in late 2012 and became engaged at the Wrestlemania 33 event in April, 2017. The wrestler documented her troubled times with John on her reality TV show "Total Bellas".
