"...I cant trust him to take care of things like a deadline. This was important to send..."
"...je had to send a email from.his email as I am nlt legally entitled to. I wrote, he only had tp press send..."
So you reminded him at least twice that we know of, and even wrote the email for him, and he still didn't send it?
He could have reminded himself, or written it himself, set an alarm to make sure it was sent on time or scheduled the email to send automatically, but did none of those things.
He made every single step of the way your problem, your responsibility, and now it's still your problem because of his failure to adult.
I'd bet all my internet money that the weight of emotional labour in your marriage as almost entirely your burden to bear.
I'd also lay odds that your marriage is characterised by you overfunctioning to compensate for his chronic underfunctioning.
Have you read "Codependent No More"?
"...He never talks yet expects me to know he is depressed and take care of him..."
"...he drinks to cope and is horrible and wont do anythjng to help himself..."
He sounds self-indulgent, entitled, immature, emotionally lazy and irresponsible.
*"...husband that...is terrible with money and wasted your inheritance and wont do anything to help himself?..."
How did he 'waste' your inheritance?
'Waste' is a blame-laden word. It implies more recklessness or irresponsibility than, say, 'lost'.
"...He says I should read btween the lines of his email saying he was having a busy day to that he was having an awfully stressful day. I did not reafmd it as such. He
never speaks up, his family dont talk. I am just supposed to guess he is having a bad day..This is why he explodes. He never talks yet expects me to know he is depressed and take care of him. He drinks a lot and does not much to help himself therefore it is hard to have sympathy..."
Definitely read "Codependent No More" and consider therapy for yourself regardless of what treatment your husband seeks or fails to seek.
His extreme inability to identify or adequately and appropriately communicate his feelings or needs is one hundred percent not your fault or problem, yet he is trying to make it so, then blame you for not meeting them. This is unacceptable, and another example of the disproportionate emotional labour and under/overfunctioning dynamic that I strongly suspect is in play.
It is not your job to scurry around like Dobby the elf, anticipating and pre-emptively addressing his feelings and needs while he does nothing to address them himself.
