Guys, My sister suggested I block a guy as I haven't heard from him in three days?

I don't really like blocking but I haven't met him. We talked a bit and kind of out of nowhere he hasn't texted in three days

I have initiated contact once before. Is It worth trying. Or.. has he just found someone else

He said he wanted to face time me. He made a playlist and named it after us... I thought it was all good signs.
