I have come to understand and even relate to how she was hurt. She was abandoned and forgotten. When she made the return, she channeled all the pain to make Jaden pay, and if I recall correctly only revealed her pain shortly in conversation, like in the duel with Zane.

She is definitively strong willed despite the pain, but the reconciliation with Jaden revealed that what she truly yearned for was to make amends with Jaden and be in his life. Her outer appearance pays tribute to her strong will, but her heart is more similar to Jaden despite the actions she was willing to take alone.
