Why has my guy friend changed all of the sudden?!?!?!

He...sounds different now!

He called me yesterday and today...his voice is no longer his, it doesn't make me feel happy anymore, he doesn't seem happy to be calling me anymore...

What happened?!?!

We are in a kind of a situation where we both like each other but didn't say it yet...he seems like he's depressed that I haven't done anything about it or that he hasn't done anything yet..and maybe never will?!?!? Is that it?!?

Maybe he met someone else, or thinks I have?

I don't understand, we were fine 5 days ago!

What the hell happened to him?
