The Elektra star made her Broadway debut opposite Kevin Kline in a production of Cyrano de Bergerac, and won high praise for her performance.
But the punishing work schedule made it difficult to balance her career with motherhood and being the wife of Ben Affleck – and Garner refuses to put her family under the same pressure again.
She tells W magazine, “(It was) just my favourite thing I’ve ever done.
“(But) it’s hard on my family. You can’t tell your kids, ‘I’m exhausted. Wake up with someone else today.'”
Garner has two daughters with Affleck, Violet, four, and Seraphina, who turns one next month (06Jan10).
