Haven't heard from him (no text)

Anonymous
So, I've been seeing someone for about four months now. I wouldn't say we were boyfriend/girlfriend type of deal, but genuinely enjoying each others company. We're "dating". He's been absolutely swamped at work, but we have still managed to keep contact through text a few times a week. I texted him last Thursday asking if he wanted to hang out that coming weekend. It's now Wednesday and I haven't heard from him. There was one other time that this happened. I texted him a few days later asking if he was okay. He apologized and said that work had become so stressful. I guess I'm just used to him texting me back within the hour.

Anyway, should I text him back or wait? I am a nearly 22 year old female and he just turned 26 a few months ago.

Thanks!

some additional notes: we always text each other back and forth. this is why this particular incident is making me feel all weird. it's not like him so that's why I'm concerned
