"It's impossible for me to express how thankful I am for having the most amazing opportunity to find my girl," Peter captioned a photo with The Bachelor host Chris Harrison as well as the cast photo for Season 24.
"To every single woman that shows up tonight, thank you from the bottom of my heart for taking a chance on me. Through every high and every low, I had the time of my life getting to know you all and made memories I will cherish forever."
Peter continued, "Thank you for being patient with me when I needed it, your grace never went unnoticed. To everyone involved in playing a part to make all of this come together, thank you. You all know who you are and we're family for life."
Peter then gave a shout-out to Bachelor Nation for all the support he's received.
"You all have been absolutely amazing," Peter wrote.
"I have felt the love non stop and it means so much that you have invested in me finding what I'm after. I hope you all enjoy the flight, we're cleared for takeoff #TheBachelor."
But that's only the beginning, as Peter teased late last year his journey on the show was "insane," andThe Bachelor host noted it was "a wild ride" for the pilot and his crew.
In addition, Peter has openly bragged that he is certain the ending of his season will not be spoiled by spoilers.
"I'm really excited for this season because I'm very confident that no one is going to be able to spoil it," Peter told The Hollywood Reporter in a recent interview.
"There's a reason I believe that, and obviously I can't say it, otherwise it gives it away. I'm very confident that Reality Steve and all of these people, they're not going to find out what happens -- there's no way they're going to find out."
Peter was referring to Reality Steve spoiler blogger Steve Carbone, who has attempted to spoil the outcome of eachThe Bachelor and The Bachelorette season for years, mostly successfully.
"I can definitely say that I was very true to myself," Peter told The Reporter of his time on the show.
"I followed my heart throughout it all. It wasn't easy, but I'm very happy that I did follow my heart. I can say that. So, no regrets."
