Valentine's Day

Haven't heard from him in two weeks, should I call or text to say something?

So I met this guy casually at a store, he asked for my number, I gave it to him, and we hit it off right away. For the next like 4 days after that we texted and called each other and talked for hours. Pretty much gave each other our entire life story and past relationships and everything until we went out on our first actual date. On the date we had a great time together and talked, eventually made out (but nothing more). He was very adamant about seeing me again but with our schedules there was never a real appropriate time so the next few times we saw each other it was basically just him coming over to my house and we'd lay in bed together and talk and kiss a little, still no sex. We started seeing each other the first of January so we said we'd wait until Valentines Day to be intimate, giving ourselves some time to really get to know each other and make sure we didn't just want sex. So we see each other about 3 or 4 more times within the next 2 weeks and then he tells me he has to go to New York City (he's originally from there) for 2-3 weeks (we live in Indiana). He says he's going with a few other relatives and he's also going to do some school work @ NYU up there. So anyway, the night before he leaves he comes to see me and we do our usual talking/kissing, he asks me if I'll miss him, I say yes, he says he'll miss me too and that he still needs to take me on an actual second date. This all making me believe he's still very interested. So he leaves and I don't hear from him for about a week, which I thought was okay because he's with family and probably very busy. I texted him one night asking if he was okay and he finally texted me back saying yeah he's good and asked how I was, I said fine and asked if he was having fun, he said yeah but he had to go because he was at a club with all his cousins but he'd talk to me later. That was 2 weeks ago and I haven't heard from him since. I've sent 3 text messages in that time, one asking if he'd made it back yet, one saying that he can tell me if he's just not wanting to talk anymore because I don't want to waste my or his time, and another saying I got invited to a VIP party and if he was back in town he should come and I haven't received anything back yet at all. It all seems very weird and out of character for him. I can usually tell when someone is bullsh*tting me and he was always very genuine and really felt a connection with him. So ultimately my question is should I say anything else to him? And if so, should I call or text? I just don't understand how someone can do a complete 180 on me, especially knowing my past and how bad I've been hurt before. It would make me feel a whole lot better if he'd even just said I'm sorry but I don't think this is working out, or something along those lines. I'm not in love with him or anything so it wouldn't completely devastate me, but I did see the possibility of it going there so I am a little disappointed.
