Husband out of town

So husband is out of town for a few weeks, and its been 3 days and our text messages/phone calls are so dry! Makes me think he doesnt miss me. He calls facetime to talk to our son and thats all. If i dont text he doesnt text. Please i dont wanna see comments about he might be cheating bcuz he is with my family at this moment. Hes always been like this. Like i just wanna have a nice talk with him on the daily basis but just dont know how because he doesnt give any effort. I also feel like i never know how to start a conversation, i really do miss him even tho its only been 3 days but we’ve been together for over 5 years and havent been apart for a while. So ladies what would you do if you were in my position? How would you start a chat/phone call with him?
