Tyler Shelton has video blogged every single day of his twenties, so when it came time to propose to his girlfriend Haylee Rose, he knew it had to be pretty special.

While the proposal itself, which took place on a beautiful cobbled street in Rome, is pretty special, it's the days and weeks leading up to it that really had us tearing up.

Haylee's father Greg passed away last April, long before Tyler ever had the chance to ask for his daughter's hand in marriage. Instead, he asks each of Haylee's three siblings for their individual blessings, and dedicates the whole proposal to Greg himself.

"Dear Greg," he wrotes in the touching video. "I'm going to marry your daughter. I always thought of how I was going to ask for your blessing one day, and now that day is here. I wish you were here to hand your baby girl off to me, so I promise to be more than you would ever want me to be." 

He continues: "I want to be the man who shares her love and patience and gives her everything she needs. I'll tell her exactly how beautiful she is, and I'll show her how to believe in herself. I will take care of her. I want to give her experiences people only dream of, and love her unconditionally, because I wouldn't want to see the world with anybody else." 

Prepare to shed a few tears watching this…
