<human>: Can you give me a shortened version of the text?

Relevant username. I had a rough childhood and missed out on the whole dating thing until now. Anyways I went on my first date about a week ago. We meet outside a local restaurant and talked for a while. We had planned on eating but we got so lost in conversation we both forgot why we went there in the first place. We talked and talked for about 4 hours.
We borh left after hours of talking and had planned to go out again sometime (no set date, we are both busy). That was a week ago and we have barely talked since. 
I feel I am making way to big a deal out of this. Is it possible she is so busy that she can't text? Or am I being a newby noob and not catching somehing.
Final question: Is there anyways to tell if I have blown it? She doesn't seem like the kind of girl to just leave someone hanging, although I could be wrong.
<bot>: Went on a date, went really well. Agreed on a second date but haven't heard from her since. What do?
