Ethan Hawke tells the November issue of Mr. Porter’s that, “Sexual fidelity can’t be the whole thing you hang your relationship on.”

The actor was rumored to have cheated on Uma Thurman with the couple’s nanny Ryan Shawhughes, to whom he’s now married.

“My relationship with my present wife is thrilling to me and I’m committed to it. But neither she nor I know what shape the future will come in. Sexual fidelity can’t be the whole thing you hang your relationship on.”

“If you really love somebody you want them to grow, but you don’t get to define how that happens. They do. People have such a childish view of monogamy and fidelity. ‘He’s cheated so he’s bad, she’s cheated so she’s bad,’ as opposed to a recognition that our species is not monogamous.”

YIKES!
