Should I ask my crush how he feels about me?

So my crush eats lunch at the same lunch table as me and is friends with my friends (it’s a small school). He’s replied to my Instagram stories a few times which led us to talking about our favorite bands. After some time, I decided to message him last Tuesday, and we’ve been talking every night since then. He continues the conversation, and says, “I agree” to about every idea I say, and is super nice. He also started a conversation one of the nights. We’ve talked about where we live, our parents, music, and other stuff. Should I ask him how he feels about me, or wait longer?
