Corinne Olympios is opening up about her past.

Shortly after filming the 21st season of The Bachelor, the 25-year-old did receive a proposal and an impressive sparkler — but from an ex-boyfriend rather than Nick Viall.

“I did not see it coming,” Olympios tells PEOPLE of the surprise proposal. “It kind of just happened. He was communicating with my parents. It came out of nowhere. I literally went out to get chinese food and I came home and he was there with his parents. It was a lot of crying and a lot of talking about things that have happened in the past and things we need to work on, and he just got down on one knee, and he had a ring with him.”

During an appearance on The Morning Breath show on Tuesday, Olympios revealed she had been engaged before, but not a lot of people knew about it.

“We were engaged for about three months, we broke it off because things were getting way too difficult with the show airing and things coming out on air that made him uncomfortable,” she tells PEOPLE. “It’s one thing hearing about it and then one thing seeing it. It wasn’t working. He was back to his old way, I was back to my old ways.”

Although Olympios, 25, didn’t reveal her former fiancé’s name, she did share a few details about him on The Morning Breath.

“So I removed two tattoos that I had, because I was engaged to a very religious guy,” she said. “And he was like, ‘I can’t marry you if you have tattoos.’ [So I] got them removed. Then we broke off the engagement.”

As she tells PEOPLE, “It was hard for me because it was constant on and off. Which is never okay, but it’s something I was used to with him. It was like, ‘Give me the ring back,’ and, ‘Get the ring back,’ and, ‘Give the ring back.’ It was just really hard. I feel really good now. There were some times that I missed him, but it’s been a while, so I think we’re okay now. I feel like we’re both in a better place now. Something like that is not easy to get over, but it was way too hard at the time. It just wasn’t right.”

Now, Olympios — who was recently named the face of Riot Society‘s female line, Riot Girls — is focusing on her own fashion line and looking forward to what’s next.

“Because Team Corn was so successful the first two release, Riot Society decided they wanted to merge and create Riot Girl, which means all my stuff will be going to retailers in 2018. It’s really exciting for me!”

She adds, “Fans are really excited. The clothes are cute, comfortable, and fun. Everyone can wear them and fans are really excited that they can buy them in stores — like Urban Outfitters, PacSun and Tilly’s — and not wait for them online.”
