Hannah recalled having doubts in her mind and heart about getting engaged to Jed on The Bachelorette's fifteenth-season finale in 2019 in her memoir, God Bless This Mess: Learning to Live and Love Through Life's Best (and Worst) Moments, which hit store shelves on November 23.
Hannah wrote that she knew her husband wasn't in the room on Night 1 of filming The Bachelorette and she should have trusted her gut once Jed popped the question at the end of her season, Us Weekly reported.
"I was caught up in the magic and the fantasy of it all when all of a sudden he got down on one knee and pulled out a ring, and I thought... No. I can't. This isn't what it is supposed to be like," Hannah shared in her book.
"I said yes anyway. It's hard to explain how conflicted I felt. Jed hadn't done anything wrong. I cared about him. And the engagement itself was dreamy -- but it wasn't necessarily my dream."
Hannah said the panic really set in once she was about to start a life with the aspiring country singer in the real world.
Hannah said after the finale taped, she realized she didn't even know Jed's real name is Jared until she saw his plane ticket.
"It freaked me out. How could I not know my fiance's full name? Who was this person? I asked Jed, 'Why didn't I know your name?'" Hannah wrote in her book, according to Us.
"'I never went by that,' he said. He didn't think it was a big deal. But alongside everything else, it just made me question whether any of this was real."
Hannah added, "How could I be engaged to a man when I didn't even know his name? And his name was...Jared?"
Hannah confessed she was completely torn over whom to choose as her winner after her romantic overnight Fantasy-Suite dates.
Because she had slept with Peter multiple times, Hannah reportedly felt like she couldn't send him home. And after being "completely open" with Tyler and making out with him "like crazy," she woke up thinking, "I cannot lose him," according to the magazine.
And Jed, whom Hannah slept with after Peter, was apparently "the only one who didn't feel so confusing."
Hannah reportedly compared her final decisions -- after an "exhausting" and "demanding" dating process -- of Season 15 to a game of MASH.
"The lack of sleep and loss of contact with the outside world made me feel like I was losing my mind at times," Hannah wrote.
"There were days when I honestly couldn't see straight, or think straight, but I kept going because I didn't want to let anyone down. Especially myself."
Hannah ultimately dumped Jed about a month after his marriage proposal because he had lied to her about his dating history.
Jed initially told Hannah that his romance with ex Haley Stevens ended one week before taping commenced, but Haley told People in June 2019 that Jed had left Nashville to film the show in March of that year still dating her.
Haley also alleged in her interview Jed had said he was only going on the show to promote his music and they'd resume their relationship once he returned home.
Jed quickly became a controversial figure and the target of hate as The Bachelorette fans rallied around Hannah during and after the finale aired in late July 2019 on ABC.
Jed apologized for his behavior multiple times on the finale and insisted he truly loved Hannah, but it just wasn't enough to convince Hannah to stay in the toxic relationship. The former couple apparently had problems even before the Haley incident occurred.
Hannah asked Tyler out on a date during The Bachelorette: After the Final Rose following her split from Jed, but it only resulted in Hannah and the former Florida general contractor spending one night together at Hannah's place in Los Angeles in August 2019.
"We avoided each other at first, until I got up the courage to walk right up to him and say hello. I didn't want it to be awkward," Hannah explained. "He said he was doing good, and I said, 'Good. Good for you.' And that was about it."
Hannah found her friendship with Tyler at the time confusing and heartbreaking, and the former Alabama beauty queen is now happily dating model Adam Woolard, whom she has been romantically involved with for about a year ago.
