Since the tragedy, Diaz has moved on in his life. He was reportedly dating a woman named Heather Nikole around 2015. But the details of their relationship and breakup were never public knowledge.
With that said, the 38-year-old has not been romantically linked with any woman since the split. His Instagram is also void of hints of his personal life.
Ergo, it is safe to say that Diaz doesn't have any girlfriend, let alone a wife, at the moment. Instead, he has been focusing on his career since returning to the octagon. He fought Robbie Lawler at UFC 266 on September 25, 2021.
