I texted my boyfriend something he hasn't responded in a few days but he also hasn't blocked me on whatsapp, etc. WHAT should I do?

He's also very busy. I made a comment about I'm sorry for "bothering" him - he didn't say I was directly, but I texted him a bit that day - and then he behaved like this - not responding to texts, etc.
