Am i being greedy?

My boyfriend and i are in a long distance relationship but he comes to stay with me at my parents for a month at a time every other month. They drive us around places and buy him lunch and dinner and snacks EVERY day. He has a job. We both graduated college already. He just asked me if he should buy airpods when he has headphones that work. This sounds trivial..but after all I have bought him (a lot) and my parents, out of the three years we have been dating since college, he has gotten me red mango twice, a cookie once, and a $20 thing from nintendo. I have gotten him dinner about half the time in college (2 years). Am i being greedy/selfish thinking he doesnt get me enough things? I buy everything myself and im not a materialistic person when it comes to wanting gifts (i actually hate accepting gifts), but when i look at the relationship, money wise, it is so skewed. Am i just overthinking?
