Sam Worthington and girlfriend "just enjoying the sun"

Sam Worthington claims he currently has no plans to marry his girlfriend Natalie Mark.
While some celebrities I can think of seem happy to rush into marriage as quickly as possible, it seems that others like to take their time and just enjoy being with each other.
Sam Worthington, who stars in the new film Clash of the Titans, has revealed that he currently has no plans to start wedding planning and marry his girlfriend Natalie Mark.
He told Confidential that the pair are "just enjoying the sun" at the moment and it seems as though his partner has enough to put up with just being his girlfriend.
Speaking of his fame, Worthington said: "She didn't ask for this kind of life. She's been thrown in the deep end and handles it the best she can."
That's what a relationship – and certainly marriage – is all about though, isn't it? Making sacrifices for each other and being happy to compromise for the one you love.
I know I've certainly heard of couples who have changed their wedding invitations and plans to suit each other and in my opinion, its this attitude that makes a marriage work.
What would you be willing to give up on your big day for your partner?
