Am I selfish?

I’ve been with my boyfriend for a year and a half. I’m somewhat of the breadwinner, I’m the only one who constantly works long hours. We’re both college students, which puts a lot of pressure on both of us, but gives him no reason to not find a job. Now, my question is: my boyfriend sells items, and with the money he receives, he spends on carts and such. He never saves any to even at least bring me home McDonald’s or even to go on a “date night.” I suppose you can say he’s more dedicated to that than to me I guess. I spend so much money on him, so I don’t understand why he can’t see through that and start helping me more. Am I selfish here, or do I have a valid reason to be upset.
