Crush Help

So recently this guy started texting me and talking to me again. We have known each other since 4th grade and he had a crush on me in elementary and a little bit in middle school. I’m starting to take some interest in him but I’m not sure if he is. He was the one to text me and he was asking if I was talking to anyone and saying that I’m attractive. He is kinda hard to read through text because he said what I just said, but he leaves me on read or just doesn’t respond even today, he just didn’t respond. I mean he could be doing something but it’s been hours and still no reply. Could he like me again? I can’t tell if he is even interested in me.🤷‍♀️
