It's been years since Sophia divorced from then costar Chad Michael Murray due to an alleged cheating scandal involving a’ One Tree Hill’ extra.
Without referring to her ex-husband by name Bush looks back at their brief romance in Cosmopolitan's February issue.
“In my 20s, when I was starting out my career as an actor, I wasn't looking for a relationship, but one found me and became serious, even though I hadn't planned to settle down until my 30s," she wrote in an essay for Cosmopolitan magazine. "But when the person you're with asks you to marry him, you think: This must be happening because it's supposed to."
"But I refuse to let that one relationship define me, which is why I've done my best to avoid discussing it for 10 years. The reality is that, yes, it was a massive event in my life."
"I came to appreciate that relationships often serve a specific purpose at a certain point in time, for myriad reasons. Some are meant to heal you, some are meant to teach you how to build yourself up, and some are meant to show you how to trust your own intuition," she noted.
"This reality has taught me that the relationships that don't lead to lifetime commitments are not failures. Not every love can last forever."
