boyfriend problems

So I don't know if I'm overreacting rn. I was texting my boyfriend a bit before he got out of work and he just stopped replying. Like 3 hours later I messaged him again and he wouldn't respond. I texted him w couple times before he told me I don't wanna talk rn. So I said okah text me when you do. I texted him 3 hours after that and he wouldn't answer so I started to worry and kept texting him and he finally said can you stop please and j said I will if you tell me what's wrong. Again he didn't answer so I said please and so he told me to stop texting him or he's gunna be pissed. Am I overreacting. What should I do.
