Is he interested?

Hello, I regularly chat with a man I met at a dance class. We were walking part of the way home, and discovered that we had several interests in common. One evening, he sent me a message. He asked me a lot of personal questions, often giving me very detailed answers; it surprised me but I thought why not. After class, even though there were other people, he would come up to me and stay by my side most of the time and talk with me. He suggested we do an exhibition together, but I wasn't available. He stopped the dance class to lighten his schedule. We both like the same type of music, and I suggested that we go to a concert together (I'd told him about the artist in question in one of our previous conversations); he was very enthusiastic. And he suggested we go to dinner beforehand because we weren't going to see each other any more (since he's stopped taking dance classes, and the concert is in a month's time).

I'm seeing him next week, but recently he sent me a message asking how I was, I told him I'd fallen really ill, and he just reacted with a ‘sad emoji’ and a question that I find completely irrelevant: so you missed your dance class? I told him I had, because I was completely knocked out, and he just replied with a ‘sick’ emoji. Even a friend would say ‘get well soon’, wouldn't they? Is this a loss of interest on his part or just clumsiness? I’m a bit surprised.

He’s 27 and I’m 30.

Thank you.
