“From middle school sweethearts at the tender age of 13, to two teens in a crisis facing the odds together, to becoming parents and building a household together, to playfully goofing around together like children as if no one is watching; all these things and many more are the reasons I want to make a promise to you,” Tyler said through tears at the altar.

He continued his vows, "A promise that, as long as I'm alive, you will never be alone, you will never question if you are beautiful, you will never doubt that you are worthy, and you will never wonder if you are loved. You are my angel, my soul mate, my best friend. I believe you were brought into this world and destined to be loved by me, cherished by me — I anxiously await to be able to love you forever as my wife."
