He's just trying to get to know you and space out the amount of times he wants to hang out with you, especially since he is just getting to know you, he doesn't want to go for Date 3 right away and lose all the mystery. All guys will go out with you once, and then for a couple days after that just shoot the sh*t with you on the phone, its wrong for you to think they are losers because of that.
I do however, think the picture of him with a smile was complete douche baggy, and just for that this guy should lose a few brownie points.
Also agree with Marciano, girls play way more mind games than guys and if a guy seems like a head trip to figure out, its probably his reaction to something you did or said based off your indirect perception of what's going on. For instance, if I was in Alex's shoes, I wouldn't know why you are not responding back but I'd probably stop texting you and move on, then you'd be like, why the f*** he stop texting? But the real issue would be the fact that you never contacted because you didn't like the fact that I didn't ask you out again, so women need to stop with the indirect sh*t and just be like "hey, so when we down to hang out again?" you know then he would have been like, oh snap, this saturday,
