The thing is King that you also have ingrained patterns of behaviour here.
It might be very difficult for you to stop doing for your DH because you are afraid of the repurcussions to you, him and the family if you do, ie he might lose his job, you might as a family struggle financially if this happens, DH might slip further into infantile rage and depression...
But I also wonder if you are getting a payback on some level for dealing with your DHs weakness and incompetence? A boost to your own self esteem when you are shown to be the one for whom things are easy to achieve and solve? Especially as you are the one who has to sweep in and clear up DHs mess...
I am not saying this to criticise you but just to point out there may be other factors at play in your couple relationship dynamic. And that although you are saddened and frustrated by your DHs attitude and behaviour you may also get some good feelings out of being the competent sensible one. So you take control of the situation by clearing up after DH and he then doesn't ever really face the consequences of his actions... and this pattern plays out again and again...
Your DH absolutely needs to deal with his drinking and anger issues. This may require individual support via GP and/or a counsellor.
But perhaps relationship therapy might also be helpful in terms of both of you being able to disentangle old patterns of behaviour and look at how both of you can make changes in how you relate to each other. Which may ultimately benefit your couple relationship for the long term [and parenting relationship too]
But good luck OP. I know you are at your wits end with all of this and it has been a very difficult and distressing time for you
