Ferber, who has pleaded guilty to charges of sexual exploitation for the relationship, can now be publicly named because a B.C. Supreme court judge lifted the case's publication ban at Petrie's request.
The law provides for an automatic ban on the publication of names in sex cases in order to protect the identify of the victim.
Petrie says she applied to have the publication ban on identifying Ferber lifted because she wants other young people to know that it's OK to speak out.
"It was absolutely wrong and now I see like, I'm not ashamed of it," Petrie said.
"I wasn't the person who did anything wrong. I was young, I didn't know any better, but it's hard."
Petrie says she considered Ferber a role model. The two became close, and in the fall of 2010 they began a sexual relationship.
"I trusted her [when] she said it was OK and that it wasn't wrong and so I believed her."
Petrie eventually told a counsellor and her parents, after which point Ferber was charged.
Petrie says she wants other victims to not be ashamed, and feel that they can speak out.
"You can make it through it and you have people around you and you've gotta use them, you've gotta lean on them."
