he has money, looks, charm and a lovely young lover to keep him going, so he'll be ok I think!
Money - can be lost overnight, and yes it buys comfort but doesn't buy happiness, self contentedness, inner peace etc etc
Looks - can be lost overnight, mean nothing deep or meaningful and he'll age like everyone eventually
Charm - anyone can act charming.
Lovely young lover - will age, might not be so lovely on the inside, there is no way of knowing what their relationship is actually like. Might be awful!
Honestly op shallow shit like money and looks mean nothing at the end of the day. Some of the happiest people on the planet have nothing and look how many "successful, rich" people etc are miserable!
That said feel free to give yourself time to grieve and indulge in self pity. Get it out your system! :) all the best
