Wait, becoming a Hexenbiest made her stupid?
If anything, it had the opposite effect. For once she's a competent fighter and actuallyy contributes something to the team. If anything, she should be thankful to no longer be a marginalised fringe character anymore and should never want to go back to being useless again. Sorry, but being a vet and speaking Spanish doesn't make for a long enough resume to indicate that you deserve a spot on the Scooby gang.
The point is that being a Hexenbiest is
part of who Juliette is now, and if he can't accept that, then he doesn't love her as much as he thought. Juliette accepting Nick as a Grimm wasn't quite the same, as a) a Grimm and a human are not mortal enemies, b) a Grimm is not going to try to kill a human for fun, and c) he was still presumably physically attractive to her. The fact that Juliette became a Hexenbiest out of all possible Wesen is what really puts the nail in the coffin. It's hard not to sleep with one eye open if the person next to you could boil you alive just by giving you a dirty look.
I don't think either of their reactions is entirely unreasonable. Juliette had a rightful expectation for Nick to be more accepting, but Nick would have had a much easier time if she had become a warm and fuzzy Wesen like Rosalee. Nobody likes Hexenbiests, especially not Grimms.
