Why would you do that

Finally had one of the people who had my full trust betrayed part of that trust. Like im really fucking pissed off right now. You do not have the fucking right to be so fucking naive about me to be that much of an idiot when i trust you with certain shit. And then when i tell you what you did wrong because you didnt even know what you did wrong you dont respond you dont own up you dont fucking apologize. Im so mad. Why the fuck would you do that to me
