What should I do? Capricorn male stood me up

Okay so I used to talk to this guy years ago, we just regain contact again last month, I never forgot him so I reached out. I remember I stop talking to him because he was always busy he made time but always. Anyway I reached out we met up I feel days later and immediately had sex I initiated that too. When we were talking years ago we never had sex I was a virgin he was okay waiting.

We've been talking every day since I text first or he does. If I don't text he will text to ask how my day going, he ask to see me again and I told hopefully this week that just passed because of my work schedule. He went away on vacation suppose to be back yesterday bcuz he works on Sundays and we made plans to meet tonight. I haven't heard from him I know I should give him space to reach out but I'm worried what if something happened to him he went away to another country should I contact him
