Nikki Bella and John Cena called off their engagement back in April, but in the months that followed, they both spoke openly about wanting to work things out. Recently, though, Bella told E! News they were officially done. Today, August 10, which would have been the couple鈥檚 sixth anniversary, the reality star posted a cryptic message that seems like it could be meant for her ex.

鈥淵ou鈥檝e changed me forever,鈥 the text-based image read. 鈥淎nd I鈥檒l never forget you.鈥 The caption on the photo consisted of the date 鈥 August 9 鈥 and the number 6, seemingly signifying the number of years the couple, who began dating in 2012, would have been together had they not split.

Cena was also active on social media on Thursday, tweeting, 鈥淭he promises you make mean nothing compared to those you keep.鈥 Of course, the wrestler often posts similar thoughtful quotes, and 鈥 as with Bella 鈥 there鈥檚 no proof that the message was directed specifically at his ex.

The ups and downs of the former couple鈥檚 romance have played out very publicly in recent months. In July, Bella shared a YouTube video in which she addressed the state of their seemingly on-again, off-again engagement.

鈥淚鈥檒l admit my relationship, it has been a super emotional roller coaster ride,鈥 she said. 鈥淎nd I think it鈥檚 hard for people to understand because we film and things get shown a few months after and I think people are like, 鈥楢re they together? Are they not?鈥 Right now, we鈥檙e just friends.鈥

Earlier this summer, there were reports that the two had reconciled. But in July, they went their separate ways again. 鈥淎fter I called off the engagement, we tried to work on our relationship to get back to where it was, and in order to move forward with our wedding,鈥 she told E! News. 鈥淎fter much time and soul-searching alone and together, we have decided to officially part ways.鈥
