"I think" she kick you out if you are somehow unwholesome.
Don't compliment her too much (when she says "you already said that" with a annoyed face, you're already near the red area), don't bother her when she's trying to relax (evening while she's reading), don't ask strange things ("can I massage your tits?").
Other than this, I don't know if it's relevant, but I shower a lot. If you're home and smelly, you're already problematic. Collect too many of these "flags" and she kicks you out.
Maybe low traits area also a issue, but I don't know.
Oh, and I make a point of making her a coffe every time I can, when she is in the kitchen, but I don't know if that's relevant either.
Thanks
