He asked for my number, but never texted/called? 10 points!?

It sounds like he's thought about dating you but never pursued it. Sometimes guys like having girls around in case things go wrong with their other options first. He probably has you on a list of like 4 other possible girls to date. I would stop worrying about it and find someone else. If he hasn't sent a text to you then he's not interested at the moment. You may get a drunk call though..
