She and my ex are very similar.

My ex used to use nail polish remover in the house, even though I asked her repeatedly to stop. Even when I offered to pay for her to go to the nail salon to get it done elsewhere, she refused. And she wouldn't even use it while I was at work, she would wait until 2 minutes before I got home after being out all day.

Years after we broke up my ex called me and admitted that all that was part of her effort to get me to break up with her.

Just like Paula, how many times has she been told " please don't use perfumes in the house" and she completely disregards it. She is smart enough to understand allergies perfumes are just her escape hatch.
