And then The Bachelor star had a romantic one-on-one date with Sydney Hightower in Costa Rica and called her the best kisser in the pack, only to oust her at their next stop in Chile.
Fans have accused Peter of being wishy-washy and not really knowing what he wants, but The Bachelor star told E! News in a recent interview, "Listen, I definitely -- I always had frontrunners."
"People think, 'He's making crazy decisions, he doesn't know what he's doing.' I promise you I knew exactly what I'm doing," Peter claimed.
"The show and the process of show, you have to give out so many roses every single week so you have to keep around people. But I knew what I was doing. And you guys are going to see that come together here in the next couple of weeks. And the clarity that I always had will become more obvious."
Peter reiterated how certain girls had made big impressions on his heart early on and so he was never really that perplexed about whom to keep around.
"I knew exactly what I was doing, and who I truly, you know, felt something with, you know, a couple of front runners," Peter told E! News.
"I see all these comments and this hate, and I just kind of brush it off, like 'Guys, you're going to see I really was never that confused. It was confusing at the end for the girls that I really really cared for that I had a strong relationship with, but up to that point I was fine."
The Bachelor's next Season 24 episode on Monday, February 10 will feature Peter and his remaining six bachelorettes traveling to Lima, Peru for his next round of dates.
According toThe Bachelor star, it was difficult for him to develop deep connections when 10 women were still in the picture competing for his heart.

"I'll be very real," Peter said, "It [hadn't] gotten extremely serious" with "any of the relationships" until now.
"[But] that's going to change here in the next couple episodes," Peter promised.
"And I think people will start to see that develop. You know the way this show [works], just the nature of the show, when there's too many relationships, you can't have that many serious ones yet. But it'll change."
Once Peter embarks on several dates in Peru, he'll be shown choosing his Final 4 bachelorettes and then visiting the women's hometowns and meeting their families.
But in addition to having so many women with whom to split his time, Peter had trouble focusing on what's important when there was drama at every turn in his journey to find love.
"There were some moments where it's like, 'Guys just what's the truth? Like, I don't care either way, what's the truth?' [And] I only did my best to try to find that out. I don't know if I necessarily found out the full truth in a lot of the situations but I tried my best," Peter explained.
In the February 5 episode of The Bachelor, Tammy Ly accused Kelsey Weier of excessive drinking and "popping pills," which sparked an argument between the two ladies and their respective supporters.
"I had been told [about that]. I don't think it aired, but you know Tammy told me about her accusations of pill popping with Kelsey and I don't support that at all. That's not right... That was not fair at all [for] Kelsey," Peter told E! News.
"I'm not okay with, you know, a lot of stuff that I've seen with some of the women -- how they're treating each other when I'm not there -- and obviously I didn't know any of this as we were filming."
"I just don't have access to that information," Peter added. "But it's too much in my opinion and I wish that stuff didn't happen. There's drama but then that's kind of taking it up a little level, up a notch."
Another dramatic moment of the season was when several bachelorettes accused Alayah of being fake, insincere and putting on a show for the cameras.
Victoria Paul also accused Alayah of asking her to lie to production about their friendship and shared history in the Miss USA beauty pageant system. However, Victoria P. claimed she and Alayah were never really friends to begin with.
Peter admitted he was "so freaking confused" about whom to believe in that situation.
"That's part of the reason that I was okay bringing [Alayah] back... It was tough for me to let her go, and I didn't feel very good about it, and I felt like I had made a mistake," Peter confessed.
"And when she came back, I tried to do right by that and keep her there, and obviously she ended up going home again after. And that was just a decision I had to make just for the saneness of the house, really. Honestly, that was the reason."
Peter's season has yet to be spoiled by online spoilers, so fans are hoping he found love and got engaged. But for now, everyone will have to settle for teasers.
"Oh boy. I mean, I say it all the time but I followed my heart the entire time, and stuff happened until the very end, and it was not easy for me at all," Peter shared.
"But I am happy, and I'm happy with where I'm at."
