Did anyone else feel like Arma's love ending is confusing?

So I started talking to Arma and I really liked the whole progress - her being very anxious and then her relaxing, then her being amazing when there's the fire. Then her being very relaxed and getting into the company of the cigarettes was a valid response to her being anxious.

I didn't tell her to stop hanging out with the cigarettes (I thought I could gently ask her maybe) But then she wanted to light the house on fire the next day! And the more I tried to stop her the more she said she would be my enemy

And she did end up lighting the house on fire and everyone was afraid/ in a panic So I took out her batteries Then I put them back in when the fire was put out

But then Dorian said she would be devastated if I told her everything (what she ended up doing)

So the options were to LIE TO HER??

And I ended up getting the love ending??

This is so confusing - she was lied to about the most important thing to her AND the wall is burnt now AND she never got to know anything about how she was influenced (Also we were not great with this at all?)

I did want the love ending and was scared this all went sideways but it didn't but the story is a bit confusing to me
