Should I text him?

Anonymous
Known him for a month and he's on vacation...it's been 4 days since I've heard from him, Could I textz him?

We've been on 2 dates and have seen each other 6 times. Each time has been amazing... Last saw him on Tue and he left on Wed on a trip w/his guy friend. Haven't heard from him since (It's Sat). Should I lose interest? Wait for him to call/text? Or could I text him "Hey, hope you're having an amazing trip"? It's been so long since I've dates and I'm not sure what to do. We typically have some sort of contact every 2-3 days.
