Ashley Greene finds dating difficult.

The 'Twilight' actress struggles to hold down a relationship because she is constantly travelling across the globe working on the vampire film franchise and other movies.

Ashley accepts that until her career commitments lessen she will struggle to form a close bond with a man.

The brunette beauty said: "I'm always here and there - everyone in my industry is - and that's why a lot of relationships are fleeting.

"I've gotten very good at detaching whenever I have to go away for three months, which I realise is hard on friends and kind of selfish.

"You go on a couple of dates, and then someone ships off to do a movie. It's not like you're going to fly out and see them, because it's not serious enough for that."

Ashley - who plays Robert Pattinson's vampire sister Alice Cullen in the 'Twilight Saga' - admits her jet-setting lifestyle and the glamorous perks of her job have lost her friends because they can't handle her fame.

Ashley added to the US edition of Marie Claire magazine: "After the movie ['Twilight'] came out, some people said, 'You changed'. And I said, 'I haven't changed, dude. Your opinion of me has changed because I'm working on this film.'

"Trust me, my parents would let me know."
