Sophia Bush and Chad Michael Murray, who famously met and fell in love in 2003 on One Tree Hilljust as quickly came apart in 2005, when they annulled their marriage after just five months. Still, in a new essay published by CosmopolitanBush says she doesn't consider the relationship wasteful.

In the years since the couple's split, and across a handful of relationships since, Bush says she's gained perspective, and has learned that all forms of love offer valuable lessons.

"I came to appreciate that relationships often serve a specific purpose at a certain point in time, for myriad reasons," she said. "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. You call in exactly whom and what you need over the course of your life, as you are learning life's lessons. And learn them you will. Even if you try to avoid these teachings, they're coming for you. This reality has taught me that the relationships that don't lead to lifetime commitments are not failures. Not every love can last forever."

"When you take the pressure of The One off, you'll open yourself up to endless possibilities," she added.

Still, Bush admitted her split from Murray wasn't easy.

"I refuse to let that one relationship define me, which is why I've done my best to avoid discussing it for 10 years," she explained. "The reality is that, yes, it was a massive event in my life. And the trauma of it was amplified by how public it became, which was incredibly foreign and bizarre to a girl who'd been just another college kid 24 months before her life blew up."

In a January 2014 interview on Watch What Happens LiveBush was a little less diplomatic, and chalked up her marriage to Murray to a total mistake.

"We were two stupid kids who had no business being in a relationship in the first place," Bush continued. "To all the other costars who've worked it out, more power to you."
