"Though I think it is a private matter and intended to keep my break-up with Jordin personal, due to bogus and irresponsible lies being reported by insensitive media outlets it became necessary for me to comment," the singer said in a statement to ABC News on Monday, addressing the speculation surrounding his split from Jordin Sparks.
Derulo, 25, says he felt compelled to make a public statement to address the rumors that cheating and his rising status in the music industry led to the end of their three-year relationship.
"There was a lot of tension in our relationship for a lot of different reasons," he said in an interview on KIIS FM. "Every relationship has ups and downs…when you stop having more good times than bad times, it's time to call it quits."
Derulo denied any infidelity or ego problems, but he did admit to host Ryan Seacrest that time apart because of their busy schedules created stress in the relationship.
"It may have weighed on her more than it weighed on me," Derulo told Seacrest. "She was in [a] frustrated space a lot."
Though he says expectations and "pressures of marriage" were a point of contention for him, Derulo has no plans on avoiding performing songs like his hit single "Marry Me."
"I think it'll be tough to perform a lot of different songs," said the singer. "But maybe it'll be special in a different way because that was a huge time in my life."
And Sparks, 24, also seems to be focusing on the positive.
"Don't cry because it's over," she Tweeted on Friday. "Smile because it happened."
Seemingly taking her own advice, the American Idol alum was beaming at the premiere of her new movie Left Behind, which opened the Catalina Film Festival on Saturday.
"She closed the party down with her date Lance Bass," a source tells PEOPLE of Sparks's night out with her close friend. "She was being silly with her castmates and was all smiles."
As for any potential reconciliation, Derulo does not seem optimistic.
"I wouldn't say good terms, I'd be lying if I said that," Derulo said when asked by Seacrest how things are between the former couple. "But it's not a bad situation ... there's no bad blood."
