Keira Knightley is unsure if she'll find love again after splitting from boyfriend Jamie Dornan, but she's scared of ending up alone.

The actress is recovering from her split from the model she dated for two years, and can't imagine finding the time to date again.

She says, "It's nice to feel wanted, like you're being chased. It's hard to have a relationship when I'm working so much, though.

"But then you have to think, 'What is actually important in life? Is career your only thing?' If it is, then it's easy, but if it isn't, that's sad, because there's going to come a day when you're left lonely. It's a difficult balance."
