Elly also addressed the claims that Frazer cheated on her and revealed that people would approach her on Instagram telling her of his alleged antics.
"How can you really know until that person admits it to you? Frazer has definitely not admitted that to me, he's definitely always denied it," she said.
"I had the highest hopes, I was very naive and I guess caught up in hoping the best for the situation."
The 2020 Bachelorette also remarked: "I don't even know I'd call it a relationship."
Summing up her time with Frazer on The Bachelorette, Elly stated: "He might've been a bit of a s**t bloke but he was a great lesson."
The couple called it quits in December last year with Elly confirming the news in a heartbreaking Instagram video.
“It’s a bit of a quick turnaround to go from thinking you’ve found the person you want to be with forever to being single again," she mused at the time.
“I wasn’t happy for a little while there and I know from my end, I gave it absolutely everything I had.”
Elly also touched on the "rumours" and "allegations" of Frazer cheating.
"I’ve learned so much about myself. When you’ve gone through a tough or stressful time, it helps you grow and I’m proud of how Becky and I conducted ourselves," she said.
"We went on the show with the purest of intentions and that was to find love, but it wasn’t meant to be."
The blonde beauty also confessed that whilst she's cut off ties with Frazer, she's still good friends with runner-up, Joe Woodbury.
"We’re just good friends with a little bit of history, nothing more. He’s always been really lovely and respectful, so it means a lot to me that we can still be friends."
