Can I get your opinion on this little situation of mine?

I'd really liked this guy.
Let's call him Joseph.

We had been talking nonstop for at least two weeks. We'd always been friends, but we decided to really get to know each other recently.

And I know two weeks isn't much time at all, but I really liked the guy.
We talked Monday, everything was perfectly fine. We ended the phone call with our usual, "Love you, talk to you tomorrow." He had just told me that he was growing to like me a lot, and that he got me a present for when he hung out Friday.

I made him a really cute bracelet, to suprise him. It took me forever.

I texted him the next day, no response.
My friend called him, and he picked up, so he has his phone.

I texted him today, no response.

I don't know what happened. Ideas?
