He left on read?

I recently reconnected with a childhood friend. We’ve gone on about 3 dates so far. He left for Italy last week for vacation. Before he left I told him the next time we hang out I would like to do an activity which he agreed upon. I reached out to see how the trip was going and he responded. I told him I figured out what activity I wanted to do (movie date) and he left me on read. Do I reach out to him when he gets back next week? Or should I just let it be and not do a follow up text?
