Will I look desperate if I message him this time?

So there is this guy who is my ex colleague, we both left the organisation after that we didn’t have any conversations, and I like him somewhere I feel he also likes me. He messaged me after 10 months out of nowhere, we spoke for a while. Then after 3-4 days I messaged him asking I want to meet up for coffee and he agreed by saying he will let me know when he visit my city in the next year.
Its been 4-5 days we didn’t have any conversation. Should I text him? Or will I look so desperate if I take an initiative every time?

I feel he needs to take an initiative this time, as last time I messaged him first.
