And another idea OP, make her a salad, and put small strands of chicken. If you mix it well, it will be undetectableb because most people just stab a forkfull instead of examining it. When she's done, tell her about the chicken and say, "That was lesson about burning my f-ing mouth."

Why were you dating a vegetarian?

Did she use the other side of the steak on her black eye after you thanked her?

Teach her a lesson and kick her in the teeth no crazy bitch should mess with a steak.

She's a bitch and she owes you a steak. Her choices are hers - and hers alone. Are you trying to force your choices on her? Doesn't sound like it from your post. Seriously, she owes you a steak. And an apology. I abhor rude behavior.

I don't understand why people feel the need to change others. I made a choice not to eat meat but my whole family (extended too) eats it, plus my friends. I even cooked a turkey for Christmas (sans removal, because that's blech) because I make an awsmsauce turkey. Why? Because they were gonna buy the turkey anyway just as every year. And it's their choice to eat whatever the hell they want. So I make my thing, they make theirs and boom. I'm happy with my decision and the world keeps turning. This issue is a lot deeper than vegetarian vs meat eating. It's trust and respect. Or lack thereof.

Leave her. If she can't accept your manly habit, she needs a girlfriend

sounds like someone needs a new girlfriend

who does that !!

"MUSHROOM IS MURDER!1" "PLANT RIGHTS!!1" Rub it in her face about how you eat fruit-cruelty free.
