Is AUTHOR wrong in the post ? POST : So I'm roommates with one of my best friends in the world. I love living with her 90% of the time but recently she has been getting on my nerves. 

We've always been very open about sharing things. It's usually not a problem for me - we only have so much cabinet space and we don't need 2 jars of every spice for example. As long as no one uses the last of my stuff or replaced it, I've normally been very chill about. She has never used my stuff excessively. Until this year. 

She has been exclusively using my stuff. And not just a little bit. I had a jug of olive oil from Costco and she probably used 75% of it without paying a dime for it. She uses my cheese all the time. I was really excited to eat see Mac and cheese only to find that she had helped herself to the best flavors in the variety pack. She doesn't even ask and just helps herself. 

It would be one thing if she helped pay for this or if I used the stuff she bought equally as frequently, however she only buys things that I don't like (and therefore wouldn't buy). 

We only have until May in this apartment (we'll be graduating college). I'm kinda at the end of my rope with this. I don't want to rock the boat and have a miserable last semester of college and be an asshole to one of my best friends by suddenly reversing my open sharing policy. But I also don't want to subsidize all hereals because I really don't have the money to do that to begin with. I don't have a meal plan in order to save money but she still has a meal plan. 


So, WIBTA if I told her she wasn't allowed to use my stuff anymore?
