Yes i think you are a bit
I became vego 5 years ago
Vegan 4 years
I always added hubbies meat he ate veto once or twice a week (with Dahl or curries)
He said he would never be vego
A year ago he went completely vegan in a week.
Now he eats fish once a week or fortnight but that’s all.
No dairy no meat. Just fish his friend catches.

You’ve been a meat eater. You shouldn’t expect to impose it on him.
He’s your hubby , compromise.
I know a fair few vegans married to meat eaters and they all compromise in the own way.
One of them won’t cook hubbies meat at all but totally respect his choices.
The ones who weren’t respectful ended up the worst off.

Make a base vegetarian meal and add meat that is as sustainably grown and local as you can for the other family members most nights. Use smaller quantities where appropriate.
You married a meat eater and trying to force change is not going to work. Over time he might see your delicious vegetarian meals and change his mind :)

My vegan mum married a butcher. She cooks him meat all the time. She will make veggies they can both eat and bake herself a protein and fry him up his steak. She makes veggie curries and fries up some diced chicken for him on the side to add to his curry. Some nights they have entirely different meals, in that case he cooks for himself. Maybe one or 2 nights a week he eats vegetarian with her! Try and find foods that can be easily adjusted so you don't have to cook an entire different meal for your hubbs. Frying up a steak or some diced chicken, in addition to what you've already made for yourself is just that little extra effort we make for someone we love. Some nights she will make him a meal just for him such as bolognese, while she just sticks with pasta and red pasta sauce, but not every night. I think if he expected an entire different meat filled meal each night to what you're eating then that's unreasonable. You both need to meet in the middle here. Neither of you are right, but neither of you are wrong. He prob just loves your cooking and dreads not getting it anymore. Agree to one meal a week of his choosing and he can agree to one vegetarian meal with you... The rest can be made to work. It won't hurt him to make a meal or 2 for himself (and for you!) But since you don't have an aversion to meat for ethical reasons, only environmental, you can't force him to change just because you decided to and to just stop doing something you guys obviously routinely did- him work, you make meals... It's kinda harsh...

Yes. Vegetarianism is your choice, not his so grow up

He is a grown man! He should be happy you're cooking for him at all! If he wants meat he can cook it himself so you're not forcing him to be a veggie! If he wants you to cook for him he should eat what you cook

Yes of course you should.

Cook him meat.
