Input: I currently live with three others in an apartment and have done so for the past four months. I genuinely believed before the fall semester started that I would be cooking fairly often. Unfortunately, laziness led to me eating out for almost every meal. As time went on, I would stop going on grocery runs because I literally never ate at home.

Now, it's spring semester and my schedule is actually extremely busy. I only eat out. I'm refusing to go on a Costco run to buy food from a list for my roommates. I stated that if we planned meals ahead of time and I would be guaranteed to eat from it, I would be happy to stop by a market before going home and split ingredients for it. I also said I'd be happy, as always, to split anything else we need around the house. Otherwise, I can't just buy groceries that will be consumed by everybody else but me. 

I'm currently being told that I'm causing purchasing food to be a financial burden for everybody else and not being a good roommate or friend. I don't get how splitting groceries, assuming we all eat the same amount of food, even saves us money in the first place. That's not even the case, as two of my roommates, the ones complaining about it, eat disproportionately more food than me or my other roommate. 

I genuinely want to know, am I missing something here?
