We haven’t spoken in a week…should I text?

So I’m a 32F, I’ve been talking with this guy (late 30s) for about 2 months. We met on a dating app and hit it off right away. We literally would talk everyday as well as Facetime every day. He’s always traveling for work (I don’t want to give too much away) but he always works in the classical music field and travels for concerts and such. Despite him being so busy we made time to meet up with each other and hang out in person. We live about an hour and a half apart so, in person time was a rare gem but we made it work. Well, about a week ago, he Facetimed me to talk and to tell me he was going out of the country for about two months (a tour). He asked me how I felt about that and I told him I would be sad but I understood that was his job and was supportive of him. He was glad I understood and was grateful, we hung up after joking around and said we would talk soon. Since that call that day had gone by and I didn’t speak with him (reminder we talked every day up until that point). The next day early in the morning I got a text saying “hello.” I responded when I got up and told him “good morning.” since then I haven’t heard anything from him. He didn’t respond to that and at one point I thought maybe something had happened to him. Then I saw him post a story on his Instagram, it was a picture of him in Europe. When I saw that I thought maybe I had misheard when he was supposed to leave the country for his tour but apparently he went abroad a lot sooner than I thought. I thought he would probably be busy practicing and such so best to leave him alone…but then thought how posted on Instagram but couldn’t even text me?? Am I reading too much into this or do you think he’s ghosted me? It’s been a week since my text and I really don’t want to give him the satisfaction of a second text. I know that’s petty but should I just move on?
