"I've never felt so unconditionally loved by someone in my life (other than my parents) flaws and all," the lengthy caption continued. "You never pressure me to be anything other than myself. And you make me want to be the best version of myself."
Demi added: "I’m honored to accept your hand in marriage. I love you more than a caption could express but I'm ecstatic to start a family and life with you. I love you forever my baby. My partner. Here's to our future!"
