Weisz explained that she'd never had an ambition to get married before she met Craig.
Of their relationship, she said: "It's very personal, it's very private. I don't think mine's particularly exceptional apart from that we're both in the public eye.
"But I never thought I would get married. It was not an ambition of mine. It was the opposite."
In fact, Weisz - who was engaged to Aronofsky at one stage - revealed she didn't even believe in the concept of romance in popular culture before the 'Spectre' actor came into her life.
The actress also feels like she was only able to find happiness once she reached a more "mature moment".
She shared: "I couldn't relate to romantic comedies - marriage seems to be the whole point of them. Then it just happened, happily, at a more mature moment."
