Crush ghosted a piano lesson then came back: is he just flaky or not interested?

I'll try keep short. But I've been teaching a guy piano. He is 21 I'm 26. He shows interest in me and he's been asking me more about myself and remembers details like the fact I'm looking for a car etc. he's asked about that like three times...

Anyway he didn't come into a lesson one week and didn't text or anything which was weird and a bit disrespectful.. but when he came back he said he couldn't remember his excuse for last week. So he missed my class and a different class he had for theory with someone else. He also wants to get a job at this music school which is seeming less likely. But anyway he came across as flakey which was so disappointing as we have been building a connection. But I've had to keep it professional and wait for lessons to end.

My instinct was to start to pull back but he is seeming to still be interested. As I said it's all been kept professional and we don't text outside of lessons. I just wonder if his flakiness means he's not that interested or serious and is too young.
