Is OTHER wrong in the post ? POST : This is definitely a much smaller AITA than some on here, but its driving me bonkers. Context: I've lived with my boyfriend for over a year. He owns the house and pays the mortgage on it, but all other bills are split evenly... Except for groceries. Originally the plan was to take turns, which worked for a while. 

However, its deteriorated to taking quick grocery runs just to grab what we need, and since I'm the one who cooks most often (I eat keto so its easier for me to make the food) I'll typically be the one who gets groceries for dinner that night. Also among my purchases are modified versions of favorite snacks that fit my dietary needs (like Atkins bars instead of regular granola bars, or Halo Top instead of regular ice cream), which are generally more expensive than normal items.

My problem is that my boyfriend eats all my special foods instead of the plethora of things in the house that aren't keto (example, he has his own ice cream but will chow through a pint of Halo Top). I asked him to stop and his response is that he thought "we shared things equally." I wouldn't mind as much if he occasionally bought these things, but he doesn't. 

Recently I bought some keto approved snack cakes online and he immediately wanted some. I told him I only bought coconut flavor (he hates coconut). I actually got a variety pack. He caught me eating a lemon one and blew up about it because I lied to him, and we could have shared but I was being selfish, and that I was being a jerk about my food. I just dont wanna spend a bunch of money on pricey keto foods and have him eat them when he could eat regular food. AITA?
