I never thought Juliette should've accepted it. She had a great reason for turning it down. Juliette didn't even need a good reason as far I'm concerned. No one should accept a proposal if they don't want to and shouldn't care about upsetting the other person. It's too important a commitment to make just to appease someone. I think they should've went their separate ways after the cat-scratch fever but that had more to do with Nick than Juliette.
I understand that they thought they could make it through once Juliette discovered the wesen world. It still bugs me that Nick only decided to come clean with her once her life was in danger. Someone who only shares something big they've been hiding from you only when your life is threatened isn't someone you should spend the rest of your life with IMO. Especially since Juliette was already threatened twice due to him being a Grimm and she didn't know why.
However, Juliette is a grown woman and she decided to be with him after finding out the truth. It wouldn't be right to just put all the blame on Nick after that happened. She's capable of making her own decisions and it ended up not turning out well for her which isn't only on Nick.
