I am not married myself, but I do have experience living with other people who have different dietary issues. I have some food allergies, and I never expect other people to accommodate me. I always am prepared to make my own if I can't/won't eat what is being served. Now, most people do tend to be pretty thoughtful and if it is something like Friday night dinner at my mom's, of course she will have food I can eat there. But I would *never* expect my loved ones to ban something just on my account. In fact my mom serves a bread every week at Friday night dinner that I can't eat and I just don't eat it
There was one time she was having a special dinner and had to serve a special thing because of my aunt who was undergoing health issues and had certain needs. She called me ahead of time, said she was serving a main dish I could not eat and what did I want to do. She wound up making a pasta dish everyone else could eat, setting aside from plain pasta for me, and I brought my own can of lentil soup to dress it with.
Imho, part of living with other people is being respectful of their boundaries and being a good partner by looking after yourself as well as them. If he wants meat and he's the only one who plans to eat it, why can't he cook it himself? Unless he is an invalid, he has no excuse to be complaining about food someone else has graciously prepared for him. If he wants his own special meal above and beyond the family meal, he can make it himself
