You transformed my life in so many ways. I never thought it was possible to have this much love for someone. I will never forget our first kiss.”

After a series of toxic past relationships, (in the documentary, Hilton opens up about being abused by five ex-boyfriends), the former reality star told PEOPLE she has finally found the partnership she deserves.

"I don't think I was ready for it before," she shared. "I just always wanted what my mom and dad have. They're best friends, he's so loyal. I was always looking for that, but I was looking in the wrong places."

Hilton continued: "Carter actually reminds me of my dad! He makes me feel safe and happy. I finally found the right one."
