I was 100% vegetarian at one point and was married to an omnivore. Then dated one. Then had a health issue that made me severely anemic and I chose to start eating some meat again. Now, I'm a light weight omni living with a hardcore carnivore (I mean, he also eats bread, lol) and we're figuring out how to make it work.

I have dated carnivores. I found the key to it working was their level of compassion in general, and a willingness to understand other ways of being. Kind of like with differences in beliefs !

Yes. Been there do it again

Of course. My wife is an omnivore. She's also a christian.

Why not as long as they are atheist.

My SO is now mostly vegetarian eating about 90% plant-based. I did not tell him to become or make him vegan but I only cook and bake plant-based dishes (of course, veganism isn't just about food). He can cook or eat whatever he wants on his own if he likes. He chooses not to eat meat and he only eats a small amount of dairy products. We both enjoy our meals and the health benefits.

If for some reason I'm back on the dating scene looking for a new partner, I would NOT date an omni. I almost cannot go to a restaurant with friends anymore if they eat meat. I almost cannot go to a restaurant/home that serves meat. I'm just fine being alone if my only other choice is to be with someone who eats meat (vegetarians might be kinda sorta ok).

I'm an Omnivore and I would date a Vegetarian or a Vegan. Could have it's advantages like, more bacon for me......

I don't see why not

If they can make a solid case for why they eat meat but not try to persuade me that I should too, and only eat meat they've made sure is produced as humanely and environmentally soundly as possible, yes, and I have done.

They'd have to clean their teeth before kissing me, though!
