I've been talking to this guy for about a month and we've been on 2 dates so far. We had actually met on a online dating site. Well our second date was last Saturday, the 13th and ever since then I haven't heard from the guy. I've tried calling him a couple of times and still no return calls. Already we've called each other at the same time everyday because we know each other's schedule and all of sudden I don't hear from the guy. I don't want to over-react but what the heck!? I'm giving it until the end of this weekend and if I don't hear from the guy then I suppose he's just not that into me and I could simply shrug my shoulders and say "So whose next in line!?"
