Aug. 3 (UPI) — Justin Bieber has broken his silence concerning why he decided to cancel the remaining dates on his Purpose world tour.

“I’m so grateful for this journey with all of you. I’m grateful for the tours but most of all I am grateful I get to go through this life WITH YOU! Learning and growing hasn’t always been easy but knowing I’m not alone has kept me going,” the singer wrote Wednesday as part of a lengthy message shared on Instagram.

“I have let my broken relationships dictate the way I acted toward people and the way I treated them! i let bitterness, jealously and fear run my life.!!!!” he continued. “I am extremely blessed to have people in the past few years help me build my character back up reminding me of who I am and who I want to be!!!”

Bieber also said he’s not perfect and will continue to make mistakes, but that he would continue to learn from them. The pop star then refers to the Purpose world tour as “unbelievable” and states that it “taught me so much about myself.”

“Me taking this time right now is me saying I want to be SUSTAINABLE,” he writes about why cut the tour short. “I want my career to be sustainable, but I also want my mind heart and soul to be sustainable. So that I can be the man I want to be, the husband I eventually want to be and the father I want to be.”

“This message is just an opportunity for you to know my heart, I’m not expecting anyone to understand, but I do want people to have an opportunity to know where I am coming from!” Bieber said.

Bieber announced in July that he was canceling the remainder of his tour. “Justin loves his fans and hates to disappoint them. He thanks his fans for the incredible experience of the Purpose World Tour over last 18 months,” a statement on his Facebook account said at the time.

Shortly after the cancelation, Bieber made headlines again when he hit a photographer with his truck after leaving church. Bieber attended to the photographer who suffered only minor injuries.
