What does it mean if my teacher does these things like teasing and fake punch my arms?

I’m 30, and My teacher is 50, I was his only student for my internship for 7 weeks. Every day, there were some moments where he playfully teased, not insulting, me by slightly fake punching me too. It was not annoying at all, but I was noticing he did that.

When my internship with him ended I left and said to him thank you for everything, since he was my teacher for those weeks. When I got home, a few hours later, he texted me, “it was a pleasure to have you” with exclamation marks. No teacher of mine ever personally texted me like him.
So what does this ALL mean, did he text me cause he’s really attracted to me or just likes me as a student?
