Is he into me?

Hello!

So I recently tried "online dating". I must admit that I was against it at first but my roommate convinced me. Anyhow, I started talking to this cute guy who's 4 years older than me and a recent college graduate. We had so much in common, it was crazy. By "so much in common" I mean everything basically, except for the fact that he's a boy and well, I'm a girl. We both enjoy volunteering (both of us have volunteered abroad), travelling, the same kind of music and movies. We also both are close to our family and have similar hobbies. So we continued talking for a while and then exchanged phone numbers. We kept on saying how we should go on a date soon. But it never happened.

I had to leave to go abroad so we didn't talk for a while. During that time, I realized that he blocked me off Facebook (for no apparent reason since in our last chat he said he wanted to meet me). So I texted him when I got back and we were talking about going on a date (for the thousand time). We didn't plan anything but told each other that we would get back to each other on the day of the date (which was the next day). So I texted him to next day and never got any reply. It's been two days now.

I don't get it. I always get the vibe that he wants to go on a date with me since he initiates most conversations and he's the one bringing up the ideas of dates but he didn't reply when the time came and the Facebook thing got me wondering.

Thanks for your help!
