Was i wrong? Warning - it’s long but plz read until the end

So I’ve already posted about having a friend live with us for 3 months until she gets on her feet. Her job doesn’t start until a month after she’s been here. Anyways she’s always acting so stuck up and better then everyone and like such a neat freak and germaphobe. For instance my 6 year olds eye is red from allergies and he asked her for a hug and she told him no because he’s contagious and not to touch her son THEN she came and laid in my bed where my son was just laying so I told her that made no sense, then last night she was too lazy to fix her own food so she asked my husband to and she told him not to pit paper plates in the microwave because it causes cancer. I told her that she will be fine and they say damn near everything causes cancer these days and that the plastic water bottles she uses are “linked to cancer” then she got mad and started saying that “Americans don’t take anything seriously and that’s why we’re all obese and wondering why we’re so big” she’s skinny and from a diff country so I feel like she was throwing shade at me and my husband (were over weight) and she literally doesn’t bother to clean anything but acts like she’s such a neat freak. She won’t let her son ever sit on our floor or touch it when there’s nothing on the floor. Anyways after she was being dramatic about my sons red eye I told her to get out of my room and leave me alone. Was i wrong?
