Shaquille O'Neal shares cryptic social media post following ex-wife Shaunie Henderson's memoir where she questions her love for him.

O'Neal responds with "I understand" and acknowledges his ex's confession, admitting she wouldn't have been in love with him either.

Shareef O'Neal supports his dad, calling him the "most lovable" person "on the planet" in the post's comments.

Their relationship, starting in the late '90s, ended in 2009 when Henderson filed for separation.

Henderson revealed in her memoir that she was in love with the idea of marriage and building a life together with the man she had a family with.

O'Neal and Henderson have four children together: sons Shareef and Shaqir, and daughters Amirah and Me'arah.

Henderson found it easier to open up in "Undefeated" after her ex-husband publicly admitted to his infidelity during their marriage.
