What am I doing wrong

What does this mean? The man I am dating seems to be annoyed every time I open my mouth. I’m not an annoying person and I don’t say stupid things. I asked him last night after he got off work “are you feeling really tired”? He snapped off. He said “why would you ask me that? That’s a dumb ass question. I just worked a 8 hour shift of course I’m tired”. I didn’t say nothing I just changed the subject because I’m so use to him reacting that way anytime I say something. Any other person would’ve said something like “yeah, it’s been a long day” or something along those lines. I don’t see how that question set someone off. What am I doing wrong?
