Drew BarrymoreDrew Barrymore has said she doesn’t know how to behave to make her relationships work.

The Music & Lyrics star has had two brief marriages and a string of more successful longer term relationships with the likes of Strokes’ drummer Fabrizio Moretti and comedian Justin Long - but they’ve all petered out.

She told OK magazine recently: “I’ve never really understood how I should feel or behave in a relationship.

“I didn’t have the kind of childhood which would have given me any perspective on what a happy home life or relationship would feel like.

“My father was literally out of his mind and my mother was more like a friend. She’d take me out to clubs and I wound up feeling like part of this very unreal kind of world, although that was the only world I ever knew growing up.

“It left me without any bearings when it came to how to live in general. That obviously affects you in terms of everything else you’re going to experience. So I haven’t had as much happiness or success in my past relationships as I would have liked.”

But, she added, she doesn’t get too down about her single status: “What’s helped me is having really good and close friends who I’ve always been able to rely on.”
