I wonder if people will still try to insist she wasn't betrayed after her outright saying she was betrayed...
That said I think she forgave her too easily. I know it would come off as hipocritical to fault someone for something you would do, but you have to consider humans are full of faults themselves. Its actually good story writing for a character to have consistent faults they have to work around to develope as a character. Right now she just blew up the blatant betrayal and setting up her lover to die as if "well whatever, its no big deal since if I had to pick between her and someone else I would pick her too" which isn't how that works. You can understand how someone can come to a conclusion and even agree with it to an extent while still being angry at them. She should rightfully be furious even if she understands. That's just human nature
