Arie proposes to Lauren on the After the Final rose special, telling his new fiancée, "I have made some bad decisions, but the best decision was running back to you. I can't imagine a life without you. You have shown me a love that is patient, a love that is kind, and I truly believe you are my soul mate. I'm ready to face this life with you and all that comes with it. Good and bad. I love you so much. And I want to do this in front of everyone because I want to show you that I should have done this a long time ago." 

Her response? "Definitely!"
