You've only been on a few dates. Why are you EXPECTING anything from him?
Keep in mind that he could be online but not sitting in front of his computer or worrying about "alerts" on his phone from facebook.
I think you should stop your focus on a guy that you've only been on a couple of dates with and keep your own options open. Expecting things from someone who has not had time to even get to know you is going to freak you the fk out in no time.

BTW: Have you already had sex with him? Is that why you are tripping?
