Wade and Union began dating in 2009 and tied the knot five years later in Miami, Florida. Their union made the actress stepmother to Wade's three children: Zaire Blessing Dwyane, 19, Xavier Zechariah, 7, and Zaya. Wade is also the guardian of his nephew, Dahveon Morris, 19.
In 2018, Union and Wade welcomed their first child together, Kaavia, via surrogacy.
Wade told PEOPLE in April that he and Union have "worked on" their marriage over the years to strengthen their relationship.

"It's about learning each other, learning what she wants for her life and for her career and trying to support all those things," he said.
He added, "She had a career and a life before we met and she was doing perfectly fine. It's not my job to change who she is, it's my job to be part of the evolution. In this partnership, there are times when I have to lead, times when I have to step back and times where we are side by side. And I know when to shut up!"

Both Union and Wade had been married once before, and the actress told PEOPLE their past relationships only helped their marriage.
"This is both of our second marriages, and we're super transparent about that," Union said. "We didn't do it right, the first time around. There's another way — to be more collaborative and equitable. We humble ourselves, listen and we meet in the middle."
