How would you feel? Opinions?

My boyfriend gets mad at me when I don’t text back even if I’m at work!! I always respond unless I can’t, dude you can’t get mad at me for not texting you because I’m at work!! You should understand that I can’t be on my phone. (Side note I have a bad habit of always saying “lol” or “lmao”) I probably could’ve responded better but like seriously?? I was at work .
