This is the exact moment I got down on one knee and asked @heatherraeyoung to be my wife! . You just never know where life is going to take you. If you told me 13 months ago I would be engaged today I would have called you crazy. . You just can’t predict what’s going to happen. One moment you are sitting there and the next your life is completely different. . The second I saw @heatherraeyoung I knew my life would never be the same. She’s not only become my best friend but she’s also incredible to Tay and Bray. . Some of you have followed me for years and have supported me throughout my struggles. . I want to say thank you and I couldn’t have gotten here without you! . Now…who wants to see the RING??:) .
