When I got home, I told her she could go, I was good. I said this because I didn't want her to think I need her. She got very offended, and told me I was giving her mixed messages, not thanking her for making dinner etc, but then telling her to leave. Talk about reinforcing how I need to send a consistent message.
This one's easy, Dev -- treat her as you would a neighbor that you've decided to let room at your place. Would you say "thank you" to such a person if they made you dinner? OF COURSE YOU WOULD! Be civil, even polite. Just don't act like her HUSBAND right now (she has fired you from that role for the time being), or her BFF.
