What do you think???

So I went out with this guy I’ve known since the start of primary school today, we basically reunited after about 3-4 year and I feel like there was instantly a spark, we got along so well he seemed to really enjoy my company. After we had left each other to go home he text me and I told him that I thought it was a really good night and he replied with “it’s the best night I’ve had in a while”. This isn’t much detail at all but what do you guys think he is thinking??? Does he like me or is this just friends?
