Bobby Brown on Releasing New Memoir: 'I Just Had to Get It Out'

— -- Bobby Brown is getting a lot off his chest in his new memoir, "Every Little Step."

"I just had to get it out," Brown said. "It was therapeutic for me to release everything that I was holding on my heart, holding in my head ... if I didn't let it out, then God knows what would happen."

The Grammy-winning R&B singer appeared on "Good Morning America" today to discuss the book. He said the reactions are what he "expected them to be."

"There's going to be some people that don't understand, and there's also going to be some people that's anticipating the book," Brown said. "It was very important for me ... I'm moving onto a better space and a better place in my life, and I think I couldn't have wrote this 10 years ago. Right now was the perfect time for me."

In response to Brown's recent interview with ABC News' Robin Roberts, Cissy Houston — the mother of the late singer Whitney Houston, who was married to Brown — issued a statement:

"Whether I would've chosen Bobby for my daughter's husband or not is not important because the choice was not mine to make. She loved him, and I believe him when he says he loved her. I only wish he had loved and respected her enough to make some of the negative statements about her and Krissy [their deceased daughter, Bobbi Kristina Brown] while Whitney was alive and able to respond from her perspective."

Brown responded, "That's a mother of a woman and a child. She feels the same way I feel, as far as we're missing two people in our lives that we dearly love, and that's her opinion. I mean, I have my opinion, and she has hers. There's no difference. We're both mourning in the same way. When you read my book, you'll notice that my book is not about Whitney or my daughter. My book is about my 47 years on this earth, and that's all. New Edition, my marriage, my kids — all of my kids."

Brown said he has not been in touch with Cissy Houston for some time.

"I wish her the best, just like I hope she wishes me," he said.

Brown has six children, including Bobbi Kristina Brown, who died July 26, 2015. He has another child on the way with his wife, Alicia Etheredge, and he said he'll be doing fatherhood differently.

"My whole lifestyle is totally different from how I used to live," he said. "I'm getting better. I can only grow."

He added, "I do not procrastinate on growing. I just try to be better and better and better every day for my family, for my kids, for my siblings, for my friends. As along as I keep trying to grow, I don't think anything can stop what I'm growing into. I've grown into a better man."

Brown's book, "Every Little Step," is out now.
