What do I do?!

There’s this guy I like, let’s call him Dan for the sake of this,. So I’ve liked Dan for a few months now and we sit together in maths class, we have a couple of inside jokes that he mostly started and we’ve been chatting a bit on sc and we’ve been sending some rly flirty messages. The other day I had to go to maths for half the lesson time and then leave early for an exam I was taking, as I was leaving the room he shouted good luck and then whispered something to one of his friends that the teacher over heard and she said aww so I though that was a good sign but then the other day someone messaged me saying that dan wanted to meet up with me but then when I asked dan about he said that theyd made it up. Do you guys think he’s into me or he’s just playing with my feelings???
