Lauren and Ben got engaged at the conclusion of The Bachelor's 20th season in early 2016, only to announce their split a little over one year later in May 2017 due to "a combination of reasons," according to the former flight attendant.
"It naturally evolved. We had known each other before I went on the The Bachelor, and we were friends. But I do feel bad, because I went through a very hard, public breakup, and I do think I brought a lot of those emotions into me and Devin's relationship at the beginning," she admitted.
"So it's definitely been, like, a roller coaster of a ride. He doesn't understand all of this stuff, and he was very confused by [Bachelor Nation], especially at first, when all people wanted to ask me about was Ben."
Lauren admitted that getting involved with Devin so soon after her engagement to Ben ended put her in the line of fire.

"I think everyone always wants there to be someone at fault, or a reason why, or someone wants to point the finger, and I think because I started dating Devin so soon after, I was kind of an easy target," Lauren shared with ET, although her breakup with Ben was mutual.
"That was obviously hard, but breakups are hard, whether you met on The Bachelor or not. Breakups suck."
But Lauren said she's "a lot stronger" now having overcome so much adversity and her new relationship is better than ever.
Regardless, Lauren isn't rushing her romance with Devin.
"We definitely could [live together] at this point. I think just the timing has to be right," Lauren explained.
"I've just been through so much change, I think that's definitely not something I want to rush... I think The Bachelor taught me, honestly, that for me, at least personally, I want to take things a little bit slower this time around."
But in the meantime, Devin pushes Lauren to take on new projects and chase her dreams, especially in the fashion world.
"He really does push me to do things that I've dreamt of or I'm passionate about or want to do, and not push me in a way that's like, aggressive," Lauren gushed of her man.
