Can't get over a genuinely nice guy?

[Ellie]

This may sound ridiculous, but I'm stuck in a bit of a rut and advice would be greatly received.
I'm 20 and the guy in question is the same age.
A month ago I was introduced to him by a friend when I was out at a bar on Saturday night. Although we'd had a few drinks we weren't particularly drunk and we hit it off straight away...we talked for hours, laughed, he held my hand, put his arm around me and even gave me a goodbye kiss after taking my number. He told me (even though he was going back to university an hour away the next morning) he couldn't wait to see me again, he really liked me and promised he'd text.

The thing about him was that he really was kind, caring and genuine. I'd never met anyone as lovely as him...and although he wasn't jaw droppingly gorgeous...he was pretty amazing in his suit.
I went home with a massive grin on my face and I couldn't wait to hear from him.

In the next day he didn't text but he did follow me on twitter. (I know that seems a bit pathetic but it did get my hopes up..).
I knew it was exam week so after a week of silence I sent him a direct message...he replied straight away! But after a fun conversation he ignored me and hasn't spoken to me since.

I try to meet new guys but for some reason I can't forget him. No one's really matched up to a guy that I met for a few hours and I feel silly. It's easy to get over idiots...but how do I begin to forget someone who was that lovely?
