Advice what to do about him?

[alana]

There was this guy and we got on great and talked all the time. He lives 2 hours away but he asked me out on a date and I said yes. (He often visited my city so it wasn't a big problem) we talked about everything and he made it clear he wanted things to kinda go somewhere with us seeing as we'd be getting into some long distance type of relationship. Anyway I don't know what happened but one day we just stopped talking. We were meant to meet up this weekend but obviously that's not happening. His twitter disappeared for a few days afterwards and I thought he'd deleted it cos of me. Well it's back now and we've still not spoke. Every time I see him say something I feel like an idiot cos I was really into him. I want to delete him but don't want to seem petty cos so far he probably thinks I'm not bothered by all this even though I am. Shall I leave it for now or just remove him?
