Guys, Should I assume he lost interest in me?

So I met this guy while I was on vacation in Tennessee where I will be moving to 4 months. We are both flight attendants which helps with the temporary long distance part because he requests to work trips that have layovers where I currently live which I think is nice that he pursues me in that way. He had planned 4 visits to come to before we even had our first date. I met him on a flight that he was working and I was a passenger. We had to wait a month for our first date because of our work schedules, but during that time he called me a lot and we would talk for 3-5 hours each phone call and would text each other everyday. 2 weeks ago we had our first and 2nd dates which went really well and where said he wanted to continue dating me and waited until the end of our 2nd date to kiss me. We have been texting and calling each other consistently until 3 days ago when he went home to visit his family who he hasn’t seen in 3 months and to celebrate 4th of July with them. He called me and talked with me on the phone for 2 hours during his roadtrip to his parents place. Once we ended our phone call I texted him that I enjoyed talking with him and that the more I talk to him the more I like him 😊 he had said back awww thank you ☺️ I always enjoy talking with you too it was a nice time talking on the phone. I told him have a great time with your family I can’t wait to hear all about it and hearted the text. Our next date is in 2 weeks. Its been hard on me not hearing from him and makes me get scared like he lost interest because in my past of dating guys have cheated on me and disappeared when there is a lack of communication. I’m a bit insecure because of my past. Do you think its weird that he hasn’t reached out to me in 3 days or it that typical when a guy visits with family?
