“I am extremely excited, a little bit of nerves just because I know how much her family means to Kelsey. I hope that they, at the end of tonight, can feel good about us,” says Weber, 28.

As Weber sits down with the family matriarch, Weier’s mother explains the seriousness of him coming to their home.

“You walked in the door and I know my daughter. When she loves, she loves like no other. It takes a lot for her, and that’s why I guess I’m so shocked that we’re here today, because it proves you’re a very special person. Nobody’s ever done this, Peter. Ever,” Weier’s mom says.

Although she can see how “special” Weber is, Weier’s mom is concerned about her daughter being left heartbroken. “You know, as a mom of three and have gone through a divorce, nobody wants to have their children’s heart broken,” she tells Weber. “So don’t break my girl’s heart. Do you understand?”

Shaking his head, Weber says, “I do. I 100 percent do.”

Meanwhile, Weier is processing her relationship with her stepfather, Mike.

“I told him I was in love with him today,” Weier admits.

“So has he reciprocated that to you?” he asks.

Though Weier says, “I know he has strong feelings,” she confesses, “I just don’t know what that means.”

And that uncertainty has Weier worried about being left “brokenhearted” at the end of her Bachelor journey.

“Just getting my heart broken,” she tells Mike about her biggest concern. “If I come home brokenhearted,” she says tearfully, “we’ll just pick up the pieces. But it’s scary. I’m scared.”

In addition to Weier, Weber will also be visiting the hometowns of Madison Prewett, Victoria Fuller and Hannah Ann Sluss.
