Help with a vegetarian matter./ Vegetarians only please.?

I share an apartment with a non vegetarian and we can not seem to agree on the rules of conduct. The smell of cooking meat makes me quite ill (I have been a vegan my whole life) and the kitchen smells spread throughout the living area. I eat all my meals out and do not cook in the house. Am I right or wrong to ask that my housemate not cook meat when I am in the house in the evening thus allowing the smell of the meat to permeate the air. She feels that it is her right to cook meat anytime and that by asking this I am violating her rights. I have no objection to anyone else eating meat although as a separate issue clearly I would like to advance the cause of vegetarianism to save more animals. The kitchen is in an open area that can not easily be contained. Is there a way to coexist or is this a rule or house breaker. Any suggestions from other vegetarians on how to work out these types of issues. PS generally I am not autocratic or bossy and I feel bad about being so in this case.
