January Jones blames 'distance' for Jason Sudeikis split

And she admits neither of them was willing to make sacrifices in their career to make it work.

Jones tells Allure magazine, "The long distance kind of petered us out. When you date someone else who's in the industry, someone has to make the sacrifices. And if no one's willing to, then you just have to be friends. (It's hard when you have to say) 'I'm sorry, I need to go away for three months and kiss other men while you stay here.'"
