"Unfortunately everyone will just have to watch and see what I am doing there. It will be worth the wait," Pappas toldPeople in an interview published Monday.
"The women were not that happy to see me, I can tell you that," she added.
Pappas also brushed off People's attempt to confirm that (as ABC's teaser for Mesnick's The Bachelor edition implied) her visit featured her telling Mesnick that she felt she "made a mistake" by not picking him at the conclusion of her The Bachelorette edition.
"I have no idea what you are talking about," she said.
While Pappas' The Bachelor appearance will serve as an on-air reunion for the pair, it won't be the first contact the two have had since last summer's The Bachelorette reunion show. In fact, Pappas said that the two had discussed the show after Mesnick had been revealed to be the next star of The Bachelor.
"I was very happy for Jason [when he became the next The Bachelor star]. We talked a lot before we went on," Pappas told People. "I told him it would be one of the best experiences of his life and that he would form many wonderful friendships and fall in love. I warned him that it is wonderful and hard at the same time."
Pappas also revealed her emotions following her breakup with Jesse Csincsak, whom she chose over Mesnick at the end of her The Bachelorette edition. While she noted Csincsak had found a new relationship -- with former twelfth-season The Bachelor bachelorette Holly Durst -- and that she is "pretty much over dealing with the breakup" herself, she also made it clear she's still upset about some of the comments that were made in the wake of the breakup.
"Hopefully one day people will be sorry for the false accusations and mean things that they have said, often on the Internet. Although I did choose to put myself out there on national TV, there are things I believe should be kept private and out of respect for me and Jesse," she told People. "We realized that we were two totally different people who wanted totally different things and we lived our lives in totally different ways and it was never gonna work. I loved him sincerely, but it would not have worked in the long run.
She added that there was "no chance" that she and Csincsak would ever be reuniting, but also maintained that she has not lost faith in finding true love.
"I still believe in happily ever after," Pappas said. "None of my past relationship have worked out for a reason, but I believe those people have come into my life to lead me to the next person and maybe that next person is the one I am meant to go to the altar with.
Pappas also said made it clear that she's been frustrated with the criticism that, given her own relationship status, she's not qualified to serve as a co-host for Get Married, a Lifetime wedding advice show she began appearing on earlier this month.
"I have very thick skin but negative comments would get anybody down," Pappas told People. "[Get Married co-host Colin Crowie] is not engaged or getting married and the last two hosts weren't either. There is so much focus on me because I was that girl who went on two reality shows to find love and it didn't work out."
