Yes we're living together. How we deal with it? Well... like I said.
for me it is murder indeed. I find it disgusting to open the fridge and see a leg lying in there first thing in the morning. In my morals it's absolutely wrong. I want to live congruently with my values so I won't touch any meat any more, even to buy or cook it. But I don't feel ethically in a position where I could judge him. I've been eating meat for many years too. It's his life, his decision. I can decide in my own life, nothing more. So I respect his decision, he's free to do what he wants. Btw, I do things that are wrong in my own belief system too. When I look at my clothes for example, they're vegan, but probably they are made somewhere in Asia by a child paid 3 cts an hour. When I have more money, I'll buy some fair traded organic clothes. Now it's not possible yet. But being a vegan is easy and I can do it now.
For him it's really a big problem, as he wants me to cook meat for him. As I said, he's angry. It's not about having different values, it's that he wants his gf to cook for him and he wants to eat meat. I tried to explain why I feel the way I feel, but he's not interested in knowing that. He would never kill an animal himself, but as long as others do this without him knowing any details, he wants to eat what he's used to eat and he doesn't want to know what happens in those meat factories. And I don't want to support it in any way.
I have no clue how we will resolve this conflict
