"Dear HB, What a ride... I'll make this short and sweet," Tyler wrote alongside the photo.
"This journey with you is something that I will always cherish. I am so grateful for all the experiences that we shared together. You taught me so much about myself and pushed me to be a better man. I learned so much from you and so did the rest of Bachelor Nation."
Tyler continued, "You were what we all needed as a lead. You showed strength and grace in the most beautiful way. You kept it real and gave us all of you. As one chapter closes, another one begins."
