The couple, who are the parents of a 6-year-old daughter, recently announced they had separated after 11 years of marriage.
However, People.com said Cox isn't determined to make the split permanent.
"I don't know what will happen, but this is not like we're getting divorced," Cox told Australia's TV Week. "This is a separation and I think that takes a lot of courage. ... Whatever is supposed to happen will be the best thing for us. ... Sometimes you just realize, 'Wow, we actually have grown apart."
