"I think the women maybe take their time more... I think women are just better pickers, except for myself," Andi told ET. "In the future, I hope to not pick any more wrong ones."
Andi has been promoting her new book, Single State of Mind, that followed her first memoir, It's Not Okay, which mentioned her ex Josh quite a bit.
Andi admitted if she bumped into Josh in the streets, she'd probably say "nothing," but the New York City resident did recently spend some time with Josh's other ex-fiancee, his former Bachelor in Paradise co-star Amanda Stanton.
"I've shared a couple drinks with Amanda and some of the other girls like Lauren Bushnell here in New York City," Andi shared, noting however that they didn't discuss "much about the details."
"I don't think anyone wants to revisit a bad relationship. We'll laugh, 'Okay, we were engaged to the same guy,' and then it's like, moving on," Andi told ET.
"It's the same way Kaitlyn Bristowe and I joke about, 'Wow, we both had [Nick Viall] on our season. Like, Nick met both of our parents.'"
After Nick competed for Andi and Kaitlyn's hearts on The Bachelorette, he appeared on Bachelor in Paradise and then went on to star as The Bachelor for Season 21.
"We laugh about that kind of stuff, but I try not to focus on those negative relationships," Andi said, adding that she has no interest in getting back together with Nick now that he's single. (Although rumors have circulated he's dating actress January Jones).
"I think we're all happy with the relationships that didn't work out and happy to move on."
Andi revealed she is "kind of" single and documented the adventures of her dating life in her new book.
"There's a lot of funny stories, most of the embarrassment falls on myself," Andi said of the book, which reportedly includes anecdotes about several exes. "It gives this level of relatability. I think if you are going to write a book, you have to go for it."
Andi almost looked for love again on The Bachelor Winter Games, but she told ET that she didn't want to "taint the image I have of Bachelor and Bachelorette."
"I kind of feel like I left on a high note, even though my relationship did not work out," Andi confessed. "I still have great feelings and memories about the show."
The franchise currently stars Arie Luyendyk Jr. as The Bachelor's Season 22 star, and Andi believes the 36-year-old pro racing driver turned real estate agent is doing well.
"I'm liking Arie and the sensitivity and the maturity that he's bringing," Andi explained.
If she had any advice for Arie, it would be, "Prepare yourself to be exhausted, both mentally, emotionally and physically because there are long, long days ahead of you... [and] it's going to be a lot harder to break up with people than you think."
She added, "On TV, it looks like you're just not calling somebody's name and so they don't get a rose and it's over, but when you're standing 10 feet away from someone and, like, looking them in the eye and basically dumping them by not calling their name, it's pretty hard."
