Sean's advice before the end.

to think you wanted to move in with her(!!!)

i understand where you are both coming from and its ridiculous you cant work it out. here is my perspective

maddy
- has a sister she shares clothes with
- girls school and mostly girl friends sharing clothes together
- expectation that best friends share everything
- female mind which over analyses for any possible negative meaning to any event
- baggage from when you told her she is a cheap ass who doesnt pay back money
- seeing the world from the perspective of a crush on a boy, doesnt understand why everyone isnt helping her and blowing things out of proportion
- trying to get you to open up by telling you she is upset

you
- only child who doesnt share
- terrible communicator and lacking in empathy
- attention seeking / draw out situations to see what happens rather than resolve them
- "unspoken rules" about friendship, housemates etc which you will never share until you are angry, and even then not fully
- enjoys awkwardness and observing reactions of people
- passive aggressive resentment about being used by maddy however you never confront the issue in a way that will improve your friendship
- enjoying teaching maddy a "lesson"
