I wouldn't say it's just that. I can understand where you're coming from, and i can see some of it being desplayed - but it feels like she goes to an unnececery places.
She knows the prince is engaged, and know how his fiencee is feeling about her, yet she is next to the prince whenever the fl is near him.
Even if this is isn't her choice, which i can understand, in helenas and elises private conversations (that helena did not need to start or continue since elis clearly hates it) she ignors all of the things shes done so far (probably since shes too innocent and maybe also denying it) and acts like she just want to be friends. Only saying sorry for one obvious thing. And at that - something that another person did.
If she had any understanding or morals of the things shes doing, she would at leat be more understanding towards elis in private. But she isn't - she thinks about her side and basicly says the things that will make her feel better so she can go on and believe she is a good person.
Helena might have some things she need to do in order to survive , but she went further than that. She trampled elise on the way and i think (just a personal theaory) that deep down, she is awere of that. But if she'll admit it she will have to face the fact that she is a worst person than she thought she was.
That's fair too. However, Elise still has more leeway to do as she pleases than Helena here.
Thats true but Helena is crossing the line. I mean yeah she is a victim, but elise is a victim too. But helena can't really see that since she is pretty self centered. She'll never get very far like that which is pretty sad.
People like those in the comments who do not understand the position Helena may be in are EXACTLY the reason why we need/still need the #metoo movement.
