The 38-year-old actress is currently in a happy relationship with David Gardner, after splitting from husband Royston Langdon back in 2008.
And in a new interview Liv revealed heartbreak taught her things she wouldn’t have learned elsewhere.
“I had this philosophy that you should only get married once. But then, of course, that changes,” she told More magazine. “I definitely believe we have lessons we learn through our relationships. You’re meant to work through and mirror each other. It’s the thing in someone that drives you the most crazy that is maybe a part of yourself.”
Liv is mother to 10-year-old son Milo with Royston and seven-month-old Sailor with David.
Becoming a mother caused her to tap into a side of herself she never knew she had.
“My favourite thing about being a parent is that I learn so much from the push-and-pull dynamic of mother and child,” she said. “Having children, I learned about my own strength.”
Liv has a hectic life, with her two children and busy career competing for her attention.
But she has become used to the pace of her lifestyle and the star believes most modern parents experience similar stress.
“I feel like I’m conducting a giant orchestra, because there’s so many moving parts,” she noted. “It’s like, ‘Over there, you guys do that!’ And then, ‘Over there, you do this! All together now!’ It’s kind of what it feels like to be a mum, isn’t it’ In the modern world’”
Liv has an impressive professional history, with movies such as Armageddon, The Incredible Hulk and The Lord of the Rings, as well as her current part in television series The Leftovers under her belt.
However, it was son Milo who encouraged her to pursue acting even further when motherhood made her question professional choices.
“I didn’t see how I could go away for three months to make a film and be the mother I wanted to be,” she said.
“[Milo said,] ‘Mummy, I want you to go forth and make some movies,’ [I told him,] ‘But what about you’’ ‘I’ll be okay,’ [he said].”
