"I made pancake batter and apple sauce last night, for the girls to fry up, but W heated up store bought pea soup instead."
Just for herself?
"Does this mean it is better that I do not cook at all? Not go food shopping at all?"
You're overthinking things again based on the actions of your W. Just do what you want to do. If she doesn't want to participate, that's up to her.
"I don't want to be a jerk, or not be present for my d15, when family dinners together were something we always valued."
It could be that it was something that YOU always valued. That was probably your sole source of validation from your family.
"So when/if W glares at me again, I say "W, I don't care to be glared at" and walk out?"
No. You put down your utensils, look at her square in the eye and tell her.."W, I don't care to be glared at. It's incredibly rude." To show her you mean business.
"I think a food stash upstairs, my domain now, may be necessary..."
Why do you think you need to go hiding again? It's your home. Start establishing yourself in it. DO NOT start hoarding food just because you don't want to deal with your W.
"This will be a great time, but W won't see us having it."
Who cares? Just be sure you take pictures for yourself. You could always show her them afterwards but don't do it if you're trying to get some kind of reaction out of her.
"Is it important that I just have a good time wherever, or should she also see it?"
OF COURSE it's important for you to have a good time...WHATEVER YOU DO! Stop wondering if she should or shouldn't see it.
A real man does things because he wants to. The old saying of "Why did the man climb the mountain? Because it's there" has never been more appropriate to anyone than you right now.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
