I noticed this inconstancy in almost all aspects of my BP's behaviour, not only on the emotional things like love and hate for his friends, family and myself,
but also in many other subjects like what he wants to do with his life (yesterday he thought he would like to become a psychiatric nurse (!) but by evening time he was talking of building a treehome and keep goats

, last week he wanted to start a business with his brother, last month he definitely wanted to return to school, etc... . )
unfortunately in the end he doesn't do anything apart from drinking, blowing and playing computergames... .
