“Happy Anniversary my love. My favorite thing to do is make memories with you,” Hilton wrote. “Your kisses are magical. I love being yours and knowing you're mine.

“I’m just really having my ‘me time,’” Hilton said. “I just feel that when I fall in love, I fall in love fast and hard and it was this whirlwind romance…and I thought it was going to be my happy ending, and I just realized after time it wasn’t the right decision.”

She added: “But I wish him the best and one day I would love to get married and have children, but for right now I’m just focused on myself and my work.”
