You said it all, you correctly complemented my post, I think that today I understand that she was a hostage of the love of the person who, despite hurting her, loved him. For me at the time it was a great injustice because I did everything to make her smile and have fun, but it happens, today I understand that better.
Moments of injustice serve to give us experience about life, to better adapt us to the next situations we will face throughout our lives.
