How to get my boss to stop texting me after work hours?

It will be like 7:00pm while I’m preparing dinner and he will text me to update some stupid spreadsheet a monkey can do. I don’t want to take out my laptop, wait for it to load, go through spreadsheets, and update something that he can do and can wait!! It stresses me out because I hate working there, he’s been making it a habit!

I’ve been answering the few times he texted me but a couple days ago he asked another task but I was not home. He texts me again today and I haven’t answered. I’m ignoring it but I feel so guilty. I was planning answering at 10pm saying ‘Sorry, I just saw this! Will get to it tomorrow.’ Is that wrong? I’m hourly by the way.
