Why hasn't he replied yet? 12 days?

I met this guy online 3 weeks ago, don't judge or say its unsafe. I was on omegle just to talk to someone because I was bored & he came across for the same reason. We got talking like we knew each other as friends, usually I never find people I can just talk to on omegle & I gave him my number which I NEVER give out. We've been texting since the day after we met, except once 3 weeks ago since he got his phone taken away. He's been texting first most of the time literally before I'm about to text him. From what I know he's a really sweet & down to earth guy. On the 10th we were having a normal conversation & he never replied back to the last text I sent. We were talking about senior pictures so it wouldn't have been something I said that would've offended him or whatever. I texted him hey! On the 11th he didn't reply & he usually does. He doesn't seem like the one to just stop talking like other people I know. He always seems to apologizes when he doesn't reply soon & says goodbye when he has to go. Do you think he got his phone taken away again? We're both 17. We snapchatted once or twice (he doesn't have an iPhone, he used a relatives phone to snapchat) & he is who he says he is. I'm kind of falling for him because he's not a pig or douche bag. He's also only 5 & a half hours away which isn't too far away if we continue talking and want to meet eventually. He seemed interested & into the conversation & if he usually texts first, why would he ignore me? I'm kind of worried and I don't know if I should be. I texted him a 2nd time (the 14th) just asking if everything is ok & to text or Skype me when he can. That's all I'm going to send him, I'm not going to be that annoying girl. So guys, or girls, is he ignoring me? Or do you think his phone got taken away again? I remember him telling me something that could get him in trouble so maybe that's it? Sorry this is long, I'm just so confused because everything was going fine! It's been 12 days since he's talked to me.

He may have run out of things to say to you! IT HAPPENS with GUYS!
