Diane von Furstenberg analyzes her surprising marriage to Barry Diller in the next issue of Page Six Magazine, included for free in this Thursday’s Post. “Barry has loved me unconditionally for 34 years,” the designer says. “I did leave him, and I went with other men, but they always ended up being jealous of Barry and not the other way around. At the end, he got me, and I’m happy he got me. He’s the pillar of our family.” Not that it’s a normal marriage: “In New York, we don’t sleep together. I like it this way. It’s my decision. Eventually, we’ll get a place in the city together.”
