While Andi refused to spill the contents of the note during any of her press appearances on Tuesday, the show took the liberty of posting the letter to their Facebook page.
"I realize I have to move on and I mean it when I say that if you're truly happy with your decision and I haven't been a thought on your mind, then I want that happiness to continue for you," Nick wrote. "If I have to move on, I will look to find amazing with someone else [and] know that someday I will. I just know I would much rather turn my life upside down and risk it all to have amazing with you."
In the end, Andi chose Josh Murray, who proposed to her with a humungous Neil Lane ring. Read the entire letter below and check out our video recap of the season finale.
