In the meantime, Peter moved to New York in January and Kelley revealed her plans to move to the Big City during a March podcast appearance on "Off the Vine with Kaitlyn Bristowe."
"I honestly would love to have a friendship with Kelley if that's ever possible, you know, if she does come to the city, that would be, in my opinion, the best-case scenario," Peter explained.
Peter told Us that he and the Chicago-based attorney "just kind of grew apart a little bit"
"It obviously sucks, like, it was a really great relationship that I had with Kelley. I truly just learned so much. And I am so, so grateful to have been able to date her," Peter shared.
"It's just, I think, one of those things that, you know, not every relationship is gonna last. We dated for, like, 10 months, and I'll always look back on those 10 months with such fondness, but I think we just got to a point where, obviously, we had some differences and whatnot. And that's okay. It wasn't anything crazy."
In Kelley's March interview with The Bachelorette's Season 11 star Kaitlyn Bristowe, Kelley said of her revived romance with Peter, "If I could put it in the best way, I think that on my end, there was just a lot of non-negotiables in the relationship."
"Actions kind of speak louder than words and it takes a long time to figure that out," she explained at the time, according to E! News.
"If there was something that I saw as disrespectful in the relationship, I would speak on it and I was pretty vocal. Communication is huge in a relationship and there were things where I would essentially be like, 'Hey, this makes me feel like s--t. This makes me feel like this way.'"
Kelley explained things "weren't really changing" and she and Peter were "definitely struggling and having hard times."
"There was a lot of push back from both ends," Kelley recalled.
"I essentially asked him if I could have a couple of days to process it myself before we let the entire world know and I wanted to tell my family and my friends and just be able to process it within myself before I have it on blast... that necessarily wasn't granted."
But Kelley may have already found herself a new man. She is rumored to have "turned down Bachelor in Paradise because she is dating someone," according to an E! News source.
