Don't let your kindnesss get you down. Stick to your rules with your DD and don't let her bring you down. Be sure to keep your lives separarte such as when she comes upstairs she knocks first so she knows that this is your house and space. Keep your doors locked so she has to respect your space and your time with your DD. Make sure it is handled as a rental agreement if not you may find yourself stuck with an unwanted permenant house guest.
