The 32-year-old split with Barrymore, 26, in January after four and a half years together, but claims there is still hope for their relationship.
She explains, "When the going gets tough (in a relationship), I don't run. But sometimes you come to a point where there's nothing more you can do.
"You love and respect each other, but it's not working. So you amicably decide to part. I don't know what the future holds--a lot of people get back together after they break up.
"We could go our separate ways and work out some of our problems and come back together with a fresh perspective.
"But you have to learn to break the patterns you're in, that aren't letting the relationship function properly. I always leave a relationship with a sense of hope."
