If a guy don't talk to you as in texting?

Is he not interested? Its been 2 days ago when he asked me if I wanted to hang out I said no.
But in general he has his IPhone. But not even Hi?
Guys help

Its definitely not that he's not interested. I don't text the girl I have a crush on every day. Its possible he's tired of starting conversations. Maybe ask him to hang out.

Maybe he just had give it a shot and doesn't really like you, or maybe he doesn't wanna bother you with asking again
