Justin Bieber reveals he axed remaining tour dates to stay 'sustainable'

"Is it too late now to say sorry" to all the disappointed Beliebers? Justin Bieber doesn't think so.

After shocking fans by abruptly cancelling the 14 remaining dates of his Purpose Tour, the 23-year-old singer took to Instagram to share a heartfelt and lengthy apology.

Beginning the post with gratitude, the 'Baby' hit-maker wrote, "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."

"I have let my insecurities get the best of me at times, I let my broken relationships dictate the way I acted towards people and the way I treated them! I let bitterness, jealousy and fear run my life!!!," the post further read.

In his post, the 'Sorry singer also said that he was working on himself and surrounding himself with people who would help him be the man he wants to be. "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!!!"

He further wrote, "My past decisions and past relationships won't dictate my future decisions and my future relationships. I'm VERY aware I'm never gonna be perfect, and I'm gonna keep making mistakes. I wanna be a man that learns from them and grows from them!! I want you all to know this tour has been unbelievable and has taught me so much about myself. I am reminded of how blessed I am to have a voice in this world. I've learned the more you appreciate your calling the more you want to protect your calling."

Bieber also said that he's taking this time to be "sustainable."

"Me taking this time right now is me saying I want to be SUSTAINABLE. 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!," the chart-topper added.

Finishing his post in all caps, he wrote, "THIS MESSAGE IS IS VERY GRAMMATICALLY INCORRECT BUT ITS FROM THE HEART. BUT I THINK THERES SOMETHING SPECIAL ABOUT IMPERFECTIONS!!"

Bieber's tour was cancelled in July and his manager asked that fans note that the singer's "soul and well being" are more important than concert dates.
