Dearest qazqaz,
Being his friend does not mean becoming part of him.
He is a drama queen, and what you are seeing right now is what it would be like to live with him every day - only it will be worse because he will either be hating you for not reading his mind or hating himself for phrasing something wrong...and eventually all you will see is this anger and hatred and blaming.
To me, he sounds really scary.
Sorry for the lack of sugarcoating, but you did ask.
