The rumor also flying around is that he was under pressure to generate more income for DSE,and this may be what led to his suicide. Maybe he was trying to break up with her because he was already planning on taking his life and didn't want to have any feelings of guilt,...or maybe she was trying to break up with him and and the timing with the pressure from the business just forced him to crack.
