<human>: I am a full time student and I work part time. I live in a house with many of my relatives together. We've each more or less separated the house by family group. The first floor is the domain of my father and I. The second floor is the domain of my grandmother, Aunt A and her husband and my cousin "G" in question. The third & fourth floor is for Aunt H (cousin G's mother), Aunt B and again my cousin G (he has two bedrooms total).

Because my section of the house has been under renovation for the last 3 months (and counting) I have been eating meals, sharing resources (food and kitchen appliances), and generally spending down time on Aunt H's floor except to shower and sleep.

I don't make a lot of money as I work part time for minimum wages. In contrast cousin G voluntarily has gone on unpaid leave from his job and has extended his absence several times though he has the option to resume working.

Recently he has begun treating my money as our money. Though he hasn't said it as such, he feels as though whenever I go shopping I am to buy groceries for everyone with no recompensation. I don't mind buying one or two items but the last few times I have offered to pay for a few things I ended up spending about $50 dollars each time when I average about $300 a month and after I pay bills for myself I have about $100 left. Unlimited metrocards are expensive.

On top of this it's not as though I eat everything that is available in the fridge. I only eat what I pay for. It's the right thing to do and given that I know he can be petty about anything I didn't want to eat anything that he may claim is "his" (pretty much anything that is general consumption he claims as "his")

Because of this I have decided to take on some of the renovation work myself (my dad has been doing it sorta kinda not really) so I can get back into my own space faster.

Am I being selfish by initially not wanting to contribute as much and now not wanting to contribute at all?

Give me a shortened version of the text
<bot>: My cousin tries to label me as selfish if I don't buy something for him/for general consumption whenever I get food or go to the grocery store and I have very limited funds. What to do?
