Is it okay to double-text a guy? Is this even considered a double-text?

Anonymous
We’ve been hooking up for about a month. Just friends, nothing more. The last text convo we had I asked him if he had any plans.. he replied saying he was out of town for the night with friends, but asked what my plans were and I told him i was staying in, but to enjoy his night. I didn’t expect a response, but he texted back saying he wished he could join me. I replied saying next time and then he left me read (no big deal). It’s been about 5 days. Would it be okay to text him? Or has he not texted me yet because he’s not interested?
