I feel like I don't want to cook for my 'vegan' husband.
Won't he be sad that you aren't cooking him anything?
Sometimes I really hate him for this lifestyle.
Well, maybe he should cook for himself then if it's such a hassle for you.  Try asking him, I'm sure he'd understand!  Partners shouldn't expect their partners to cook for them all the time.
I know right, I have other chores that I need to do too.
Yeah, you do have so much on your plate, so your husband really should help you out more, and the first thing he can do is cook for himself if he cares about going vegan. No one has time to customize their food. His lifestyle, his choice, or start helping you out more.
