<human>: Can you condense the text into three sentences or less?

So i have been talking to this guy I met on a dating site for a couple weeks and we met up once for coffee.  I am really really interested in him, but I think I might have messed it up last night.  We had been talking about meeting him for diner this week and he suddenly stopped responding.  He usually would consistently respond to my texts within 30 minutes at most.  First it was 2-3 hours and I had just sent him a few messages about our plans.  But then it was 8pm (he hadn't answered me since 2pm) and he still hadn't responded.  

When it comes to texting I usually get anxious when I feel ignored.  So then I called him and left a message because he didn't answer asking if everything was okay.  Once there was still no response when I got home from work I started panicking and wondering what I did or said wrong to him.  I sent him a very long text message about how I get anxious and assume the worst situation when someone doesn't answer me for a long period of time. I told him he would probably think I am clingy or crazy when he read it.

Now I know he had been in Vegas for a mini vacation, but he been texting me throughout the whole weekend. After not getting a response from him for 9 hours I went to sleep pretty upset and hurt.  I woke up now and he just answered this at 1am "my phone died and I didn't have a charger.  Just got home."  No apology.  No acknowledgement of my message about getting anxious.  

My question is what do I even say to that if anything after sending him a lengthy message about my communication anxiety?  Should I just move on and pretend he doesn't exist?  Never talk to him again?  Apologize?
<bot>: Guy I have been casually dating disappeared for 10 hours and made me anxious, which resulted in me assuming the worst situation.  Should I forget about him or try to fix it?
