Sadie Frost wasn't happy for five or six years after her split from Jude Law.

The 51-year-old actress and designer admitted that it took her a long time to cope with the breakdown of her marriage to the 43-year-old actor in 2003 and she didn't feel in control.

She told The Sunday Times magazine: ''I was not a confident, happy person. Eating, sleeping and just living were all tasks that I found very difficult. I didn't feel in control of my life.''

Sadie has been dating businessman Darren Strowger for the past three years but insists she is in no rush to tie the knot again.

She explained: ''It sounds awful if I say I don't want to marry him, but it's fine as it is now. He's got his children, I've got my children, we see each other when we want to, but I love having my own space and waking up in the morning on my own and going to bed on my own. But then I like spending time with him as well. It seems to work perfectly for both of us, for the moment. I don't know how long it will carry on.''

These days Sadie - who has children Finlay, 26 (with her first husband, Spandau Ballet's Gary Kemp) and Rafferty, 19, Iris, 15, and Rudy, 13, with Jude - is much happier than she was and says she has learned not to stress out about every little thing.

She said: ''I am much calmer now. If I'm running five minutes late, who cares? I've learnt not to be so obsessive and controlling. It's nice to just engage with the moment.

''I don't really suffer from anxiety today. But I'm someone who wants to achieve a lot every day; I want to feel alive and there are certain things that make me feel like that. I want to take my dogs for a walk, I want to exercise, I want to be a good mum, I want to be a good business partner, a good actress, and that's a great feeling because I get things done and I enjoy what I'm doing. I feel pretty happy and content with everything.''
