He hasn't responded to my message for an hour, should I be worried?

Anonymous

I texted my boyfriend this morning the following "wyd, are you sleeping"

He replied with "Nope, I'm about yo help my brother assemble furniture from IKEA".

I said back "oh, you are going to do it"... because he complained about it yesterday and said he doesn't want to get involved.

The he texted back with "they called my best friend asking him to do it... and that's how I decided to go anyway".

And I replied with "they are cunning/smart ass"

He then stopped responding and I asked him "can I call you later or not"

He hasn't even read it yet, it's been an hour.

At first I thought that maybe someone has called him, but now I'm not so sure about it.

What should I do?
