What the hell dude? Make up your mind!

I'm extremely close with this guy I grew up with. We've talked about dating, but he says he's not ready. Ok, fine. But if that's the case, then why does he treat me like a girlfriend? Like he's my good morning and my goodnight, every night. And our convos ARE NOT platonic. Besides the sexual stuff, we share very personal stuff with each other too. I don't know what to do.
