We sometimes go days without texting?

Why do guys text for days on end and then suddenly just stop for 2 or 3 days, sometimes a bit more?
I've sort of been seeing this guy for a couple of months.

I understand that texting can be a nuisance for guys, but I've already texted him once and he responded straight away and we had a good conversation.

But I don't want to message him twice. I should wait until he comes out of his mancave, right?

Also, we met up twice this week already, so I suppose he wants his space for a bit?
