The Two and a Half Men
star, 33, hasn't openly discussed the reasons behind his split
from Demi Moore
, but he has addressed what turns him away from a relationship.
"I could never be with a woman who felt like she needed to change me," the actor – who reportedly cheated
on his wife of six years – tells Men's Health
in its December issue.
But that doesn't mean he's opposed to compromise.
"I think it's about working on the relationship and making it better … when it's good," he says in the interview, which he gave before the split. "The goal is not to get into a relationship; the goal is to be
in a relationship."
Not to mention keeping that relationship intact.
"I'm relatively scared of failure," he admits. "I just don't see it as something that's inevitable."
