Nick, 21, told "GMA" co-host Robin Roberts it was the band's unaddressed complications that lead the group to split. He was the one who first brought up the problems with the other brothers, Joe and Kevin.
"We're family first and that's always been our main priority," said Nick.
"So honesty within that, you know, within what we do as a group was really important. So I came to the table with the guys, just before we were prepping to leave for tour, and I shared my heart with them."
Nick said it took a long time for the group to decide on the breakup, but he believes it was best for their solo careers, and more importantly, their family.
"We feel like we're best suited to do our own individual things -- all things we're passionate about -- and choose to be brothers first," he said.
When Roberts asked middle child Joe, 24, to discuss what specific complications prompted the split, he said, "It was the music. For us we kind of held on to it for so long."
The Jonas Brothers released their first album in 2006, but it wasn't until their 2007 self-titled sophomore release that sparked their successful career. After promoting the record on tour with artists including Kelly Clarkson, Jesse McCartney and the Backstreet Boys, it peaked at No. 5 on the Billboard charts.
Six years later, Joe says the music started getting stale; the brothers began butting heads.
"At some point we decided that it was best to finish this," said Joe.
While the trio's latest hit, "Pom Poms," would have appeared on their latest album, the band won't complete the album. But don't fret Jonas fans, big bro Kevin, 25, has a special treat.
"They (fans) have traveled with us and been with us for so many years, we did not want to just leave without giving them back something. We are going to release four of the unreleased songs from the album."
The group also went back into the studio to put together the live tracks from their last summer tour.
The three brothers will now focus on their solo careers, involving writing music, acting, business ventures and reality TV.
When it comes to a Jonas Brothers reunion, they're going to work on being brothers first. Nick says, "never say never." Oh no, that was Justin Bieber. I guess you'll just have to wait and see -- 2014 VMAs?
