Should I remove him, and look for someone else?

This guy wanted to get to know me more, said I was gorgeous we have talked once a week so far. I sent him a text saying I hope you're feeling better about work.. cause he was sad about it the other day and told me about it. I didn't get a response and he has been online and stuff and hasn't spoken to me. So I'm guessing it wasn't good to do that. But I'm getting fed up. We are supposed to hangout during Christmas break. But maybe this guy is a flirt if he isn't going to answer that text, and its been three days.

Do you think I should just remove him from msn, fb and my phone. I don't think he is serious
