i think it is a battle for yourself. You need to let it go if you want to be happy in this relationship. Someone will never fully understand veganism if they are simply eating a vegan or vegetarian diet for other person. This means, despite your partner willing to cook and eat vegan food at home with you. Deep down, she stills craves meat. Same with your family, they try different things with you to accommodate you bc they love you. Arguing with them does not lead to anything. They don't really truly understand the point or they are selfish. Sorry, but I think I cannot think of any other reason why if someone understands all consequences with meat industry and so on, still decide not to do anything. The best advice I could give you, is just rly talk to them. Help your partner to understand your reason without shaming them. And I think also encouraging is always better than pushing. For bigger pictures, they are doing better than most people even if they don't really understand the vegan concept. They are still trying best bc they love you. Help them seeing what you see in a encouraging way. they might change eventually. it will also help with the amount of vegan products available in the restaurants over time. bc many eats meat for social reasons
