Is it okay if I stop texting/messaging him while he is on vacation?

I went out on one date for drinks with a guy I met online in February. It fizzled out as we are both kind of shy and reserved and likely were unsure of each other's interest. Last week I e-mailed him to reconnect, and we picked up the banter right where we left off. He was leaving for vacation soon, so I suggested he just message me when he returned. But he started to text me and we texted for 4 days before he left.

We use an app that doesn't have roaming charges, so after he left, I msged him 2 days later, just saying hope he was doing well, etc. So for the past few days, we've exchanged 1-2 messages a day. He's not coming back for another 1.5 weeks and I'm not sure what else to talk about over text. I'd rather he just enjoy his vaca.

I was thinking of just stopping texting him for the next 1.5 wk. But I don't want him to think I've lost interest. Do I have to say something before I stop texting for 1.5 wk? What should I say? "Enjoy the rest of your vaca, see you when you get back"... but I'm not sure if I like the sounds of that?
