Kim Cattrall claims acting "consumes her life" so much she can't hold onto her relationships.
The 'Sex and the City' actress - who split from chef Alan Wyse last July after five years together -finds it hard find love with anyone outside of her profession but hasn't given up hope of settling down one day.
Kim, 53, said: "It's very hard for someone not involved in this business to really understand what it's about.
"You work 12-hour days, and something like a series literally consumes your life. I think it's just time not there, really. But I'm still hopeful that I'll meet someone."
Although she keeps challenging herself in her acting career, Kim says sticking to the character she is best known for - man-eater Samantha Jones in 'Sex and the City' - would be much easier.
Admitting she is nervous about her forthcoming starring role in London play 'Private Lives' opposite 'Pride and Prejudice' actor Matthew MacFayden, she added: "Sometimes I think why do I have to do these scary things? It would be much easier just to play Samantha for the rest of my life.
"You've been looking forward to working with this director and these actors and this play and then it comes and you think, 'Oh, f**k!'... Like, 'Oh no! It's here!' You very much feel the blood coursing through your veins."
