The 28-year-old television personality discussed her conflict with Hayes on Tuesday's episode of fellow Bachelor Nation star Dean Unglert's "Help, I Suck at Dating!" podcast after feuding with the 29-year-old reality star on Twitter.
"I guess what I was so confused about is that it's been eight months and I have moved on with my life," Stanton told Unglert.
"I didn't even really consider Robby an ex," she said. "I was completely shocked that he reacted the way that he did."
The pair clashed last week after Stanton tweeted about an unnamed ex-boyfriend who e-mailed her about a payment issue with his Disneyland pass.
"It was a funny tweet. I wasn't even throwing shade at him, nor did I hint that it was about him," Stanton said of the since-deleted post, which said an ex asked her to update her debit card information for the pass.
Hayes responded to Stanton's tweet by sharing their e-mail thread about the pass and a since-deleted video of their alleged text message history.

"I feel like he doesn't even care that it made him look bad," Stanton said of Hayes' reaction. "I feel like he just wants attention, whether it's good or bad."
Stanton previously told Us Weekly she's confused why Hayes is angry.
