So his mother just died and he was going through a nasty divorce. His soon-to-be-ex wife is also his manager, so both his professional and personal lives are completely miserable. He was working long hours and he had just spent two hours in a pub where he had been drinking heavily.
You know, sometimes life difficulties are the culmination of the way you treat others (say karma if you wish) and when it stacks up this heavily against someone its usually a clue that you are being a twat and need to change your behavior, OR just push through and continue with your current behavior until the roof collapses and kills you.
Seems clear which choice he is making here.
