Hi so as the title suggests my (18m) gf (18f) routinely neglects my needs. Specifically when it comes to weed. 

I'm in college but still very much dependent on my parents and they have a 100% no cannabis rule which I just never have followed and for the most part things have worked out.

Then came my gf, she comes from a much less strict family than I so these things are a lot easier for her, but she never takes any form of precaution around my family. Which has manifested into many close calls and near misses with them and their rule.

Last night she left a bag sitting in the passenger seat in my car that she completely did not tell me about.  It's all fine until I go to take my sister somewhere this morning and opened my door to see that bag staring me in the face.

I kind of lost it on her to which she says I'm being rude about this and she didn't mean to so I shouldn't be mad at her.

So, AITA for thinking she needs to respect my rules concerning my family more or does that responsibility fall entirely on me?
