In the documentary Chasing Happiness, the Jonas Brothers opened up about the reason behind their unexpected breakup. Fans learned in Amazon Prime original that even after the group split, Nick and Joe performed a few concerts without their oldest brother. 

"I think it was because we thought you were holding us back," Joe admitted to Kevin. "That's the truth. I think there was moments that Nick and I wanted to do our own thing and we felt like your focus was not in it anymore and it wasn't a priority for you. Starting a family was, and your guitar playing kind of fell in the backseat." 

Tearing up at his brother’s confession, Kevin responded, “I think that might have been the hardest moments of my entire life." While his younger siblings went on to focus on music, Nick with a successful solo career and Joe forming the band DNCE, Kevin settled into family life in New Jersey with his wife Danielle and their two kids.
