The Grayson  Prestonex-wife of Hall of Famer Shaquille O'Neal published a memoir detailing their marriage.

In the book Undefeated: Changing the Rules and Winning on My Own Terms, which was published on May 7, Shaunie Henderson says she isn't sure she was in love with the four-time NBA champion.

Henderson and O'Neal were married in 2002 and have four children together.

"Looking back, I don't know that I was ever really in love with the man," Henderson writes. "But I was in love with the idea of being married to the man I had a family with. I was in love with the idea of building a life together. I truly did enjoy spending time with him. [NBA] road trips gave me a chance to be with my husband and experience the NBA life for a little while."

She added that O'Neal "was trying to be a world-famous, thirty-something multimillionaire with thousands of women throwing themselves at him," and a husband and father at the same time.

The couple divorced in 2011.

"I enjoyed those sweet early years being a mother and raising my children; my days were always busy with kids and family, and every now and then I got to travel or enjoy a little of the NBA high life. But invisibly, my marriage was beginning to crumble," Henderson wrote.

The day after the book was released, O'Neal, now an analyst with Turner Sports, took to social media and responded to what Henderson said with the caption, "Trust me, I get it."

O'Neal has said he messed up the relationship by cheating on his wife.

"I understand...I wouldn’t have been in love with me either. Wishing you all the best. All love, Shaq," he wrote on Instagram.
