Am I overreacting?

I’m kinda upset and trying to figure out if I’m overreacting. I rarely ask for help, it’s just not how I was raised, but I’ve been supporting my boyfriend since he lost his job two months ago. We live together, and I cover most of the bills, food, sometimes his gas, all while working two jobs.

The other night, I asked if he could drop something off to my hairstylist for me since I’m slammed with work, and he said no because it was “too far.” I didn’t say anything, but it really bothered me. I barely ask him for anything, and the one time I do, it’s a no, even though I’m literally holding him down??

Another thing that rubbed me the wrong way was on his birthday. I spent around $500 taking him out and getting a hotel, and on the way home he asked for gas money. Then later he swapped the last cold water I grabbed for himself. It’s small stuff, but it keeps piling up and makes me feel like he’s selfish.
