Chic he kicked and shattered the cats waterdish and you say it is out of frustration? It s o unds like you are excusing his behavior. He is not acting like an *adult*, he is acting like an alcoholic in withdrawal.
I fear that he may do more harm as he did to the door last year.
As much as you dislike confrontation, I think it is time to draw a line in the sand...your house, you pay the bills, your rules.
Take a ride over to the big Verizon store and tell them what you need, you can stay on the net with a low price and a tablet ( post from bed like me, lol)...at least the information will arm you with an action plan.
You can give fair notice and he will try to call your bluff, but bullsh.. is bullsh...His behavior is not acceptable, he can learn control. Professional help will also give him something else to focus on.
