Is my father mistreating me in this situation?

Salam everyone. I’m a young unmarried sister, living at home with my parents. My mother has been looking after my sick grandmother, so for the past year she's been staying with her, and it’s just been my dad and me at home. For meals, we don’t really have a set routine. Sometimes I cook, sometimes we get takeaway, and other times we grab something easy and throw together a salad or a quick meal. I work full-time, and lately I’ve been super busy, so I haven’t been able to cook much and just eat whatever I find at home. Alhamdulillah, I cover all my own expenses except for food. A while back, my dad and I had a disagreement, and since then, he’s stopped bringing dinner for me. He buys takeaway just for himself, brings it home, and eats while I have nothing. It feels really hurtful and unfair, and I’m wondering, from an Islamic perspective, is he neglecting his duty toward me as his unmarried daughter? What are my rights here, and how should I best handle this? Just to give some background: the argument happened on Eid al-Adha. We were meant to come back home together, but he drove off without waiting for me. When I called him, he hung up. I tried calling again and again, but he didn’t pick up. I also left him several voice messages, asking why he did that, telling him how much it hurt me, and explaining what upset me. Since that day, he hasn’t spoken a single word to me.
