Actress Gabrielle Union has opened up about her 2013 split from new fiance Dwyane Wade, revealing she was trying to do too much at once - and her relationship suffered.

The 41-year-old star tells Glamour magazine that she has recommitted herself to the basketball ace after briefly putting her career first.

She explains, "(We split) because of distance and scheduling. I finished filming the show (Being Mary Jane), then I flew to Vegas right away to start shooting (film) Think Like a Man Too. I couldn't take time off, and I missed some quality togetherness we desperately needed.

"Over the summer, I reassessed priorities. I'd always wanted an awesome career with back-to-back projects, but I realised I wasn't willing to sacrifice my relationship for it. Moving forward, I decided my work schedule has to make sense for our family.

"If your relationship isn't something you're willing to give up and you can compromise, do so."

During the break, Wade fathered a child with another woman. Union has yet to address the baby story, which her fiance has confirmed, but reports suggest she was well aware of the child when she accepted the sportsman's proposal just before Christmas (13).
