"I've never gotten so much judgment in my life about how old I am," the 22-year-old nanny toldPeople.
Although other women in the cast were in their early 20s, Bekah seemed to be the only bachelorette who received heat and criticism based on her age.
And 36-year-old Arie, himself, even questioned whether Bekah was ready for a serious relationship and ultimately marriage. During a three-on-one date in Tuscany with Tia Booth and Kendall Long, Arie chose to let Bekah go because he simply didn't think they were on the same page in life.
"When I left, the oldest person there was still nine years younger than Arie," Bekah explained.
Arie did admit on the show that he was trying to talk himself out of his feelings for Bekah for quite some time. Because when they were together, Arie appeared absolutely smitten.
"I think he was afraid of his feelings for me," Bekah insisted.
"I think he was looking for an out the whole time, and my age was the perfect thing. Had I been 27 or 28, he would have interpreted my energy and my attitude as part of my personality -- whereas since he knew I was 22, he interpreted it as signs of immaturity. So it was frustrating."
It seemed like Tia also played a role in Bekah's exit, as the 26-year-old southern belle warned Arie moments before he had to hand out his last rose in Italy that Bekah was not ready to settle down or be his wife.
"I simmered on it for three months," Bekah admitted to People of Tia's conversation with Arie. "I wanted so badly to be able to just let it go. But every time I would think about her, I would get livid. Watching it again, I wanted to throw something at the TV."
Bekah added, "All of Tia's time and energy was focused on talking about me in a way that I felt was very unjustified. It sucked."

Bekah missed out on bringing Arie to her hometown, where he'd meet her family. But according to the free-spirit, her romance with Arie probably wouldn't have worked out in the long run anyways.
"I do wonder if our lives weren't super compatible outside of this experience," Bekah said of the pro racing driver turned real estate agent.
"It's funny. The things he wants that he attributes to being 36 -- like, 'I just want to go to bed at 7PM and start popping out kids,' I don't know if I'll have that attitude when I'm 36. I don't think our ideas of marriage and a family life were really the same. And also, I didn't want to move to Scottsdale!"
