She was obviously unhappy at the palace, but seemed to be able to live with it. I think having to marry a stranger was what eventually pushed her to try and do something about her life.

i think if she was given more role to play than being just a pretty princess, and allowed to see more of the world, she wouldn't have been so vehemently against the arranged marriage. She'd have much more criteria to be able to evaluate arrange marriage from different perspective. She didn't want to be stuck again for the rest of her life, without even experiencing it first. And that's what stopped her to put her faith in arrange marriage because she saw it as another restriction

Both actually, but this one is the most.
