Would you take this?

DP had a very stressful job. Tonight, he snaps at me and tells me to ‘fuck off and shut up’ in a nasty tone.

All because I couldn’t get his food out the oven the second he asked me to (I was doing something and had wet hands). Apparently that makes me selfish. He was working late, so got up in a strop to get the food out himself and dropped his laptop, which is when he lost it.

99% of the time he is great to me and we have a lovely relationship, we love each other etc but when he speaks to me like this, I want to just walk out. Is this normal!?

This is unvarnished verbal abuse. You should NEVER take this, you will be opening the door for future abuse. If there are no consequences, that’s a green light for him to continue.

You must act, and quickly. What would you like to do about this?

No, I wouldn't take that. There would be Ructions if DH told me to fuck off.

But he wouldn't ever say that to me for fear that I'd take him at his word, and then that's his happy life ruined, isn't it?

If its a one-off then I'd just think he had a bad day, he dropped his laptop after all. However, do you always have to do what he asks, immediately and just this once you were unable to? Do you walk on egg shells around him?
Years ago I pulled the washing machine out but accidentally pulled the water hose off, water spraying everywhere. I was soaked. I called DP to ask for help. He came round, took one look at me and burst out laughing. I told him to FO. He did!
I saw the funny side later and I didn't blame him for FO.
Maybe next time try it back on him? Or just walk off/out?
