"I can safely say I don't know," the actress, 38, tells InStyle for its September issue. "If it's meant to happen, it will. I love and adore being a mother."
Thurman says parenting her two children (with ex-husband Ethan Hawke), Maya, 10, and Levon, 6, is "the greatest gift I’ve ever been given."
The actress – who announced her engagement in June – adds: "I understand that raising children is universally difficult and that people read an article hoping for something worthwhile in it. The truth is, I am not on some inside track. I have no incredible revelations to share."
As for what she looks for in a man, Thurman says, "Confidence, intelligence and goodness. There's nothing sexier than that combination."
And while no wedding date has been set, Thurman confirms that she likes to be married. "I crave structure," she says. "I've never had good habits or a formula for how to shape a day, a month, a life, I appreciate anything that makes me focus."
