For context, my boyfriend and I have been together for about half a year and I normally drive 30 minutes to my boyfriend's apartment since he doesn't have a car while living on campus. I asked him if he had water I could drink and he said "No." I got annoyed by that and asked if he was joking. He's often sarcastic, which I don't usually mind, but I was in a bad mood that day. He said that if I wanted water I could go to the bathroom sink and get some myself. I'm not really sure if I was acting entitled or if he was being rude? I didn't demand for him to get it for me or anything and just asked if he had water I could mix into my drink (I had previously just bought us both a meal for us to share).

I had been annoyed by something that had happened earlier and that comment just made me extra mad. I think the least he could do is not answer sarcastically to me when I ask a simple question, given that I had just driven 30 minutes to his apartment and paid for our food -- in addition to this, it's just water from his sink and the gesture of him getting something for me would have been nice. He also rarely pays for my food (since I don't want him to think I'm using him for money) and I drive to him every time we hang out. I will admit I can be a bit bossy sometimes without intending to be (asking him to hold my purse, telling him to turn the lamp on without saying please, etc). I just can't tell if he's being rude or if I'm just overreacting. I also feel like I'm reading way more into this than I should be but his tiny remarks make me feel highly annoyed.
