She does not tell him but blames him.
Nick: Why are you doing this?
Juliette: I guess I'm just trying to be the best Hexenbiest I can.
Nick: You don't have to prove to me that this is my fault.
Juliette: That's what you think I'm doing?
Nick: Juliette, you're not even giving us a chance to figure this out.
Juliette: What do you want to figure out, Nick? How a Grimm and a Hexenbiest are just gonna live happily ever after?
Nick: You don't scare me. And I'm not letting go.
Juliette: Aren't you scared of what you might do to me?
Nick: I could never hurt you, Juliette.
Juliette: I wish I could say the same. But I just don't know anymore, because deep down, I do blame you for what's happened to me, and part of me loves you for it, because I have never felt like this before. It's ironic, isn't it? You've been the special one for so long. You're connected to a world that most people will never know or understand. And now I know and I understand, and I don't want to give it up, just like you didn't want to give it up. And now I know why. Once you're in it and you've... seen it and tasted it and... lived it, you can't go back. Everyone else just seems blind. I like this power, Nick, and I know you do too.
Nick: Stop it!

A toxic person, as one would say today, in what became juliette.
First rejecting it and then wants him to choose it and getting angry because Nick only seeks to protect Adalind
