I agree that you did the right thing, although it is hard. "I'll pay you back right away because I am evicted and don't have to pay rent"? which means she wants to invade back to your house?
you won't have any peace if that happens.
sometimes they have to learn the hard way that respecting mom and dad's house is necessary if they want to live there and have all the privileges that come with it.
congrats on not being a doormat.
