Hi all, I am a little out of my depth here so I'd love some advice.
I went out with a guy for the first time on Wednesday. He is a friend of friends.
The date went really well, good conversation and chemistry. Before the end of it he had already asked me if I wanted to do something on Friday as the weather seemed to be good and he wanted to see me again. There was a little kiss at the end and he then messaged to say how much he enjoyed our evening together and that he looked forward to seeing me again.
This morning he texts asking how I am and sending me some pics of where he was. I then asked if he wanted to watch the football game tonight, in which case we could perhaps meet later in the evening instead of early on as we had already agreed?
And then.. crickets.
My last message was at 11:40 am, he has read it and never replied. I am a little shocked as I have never been stood up 
What is the etiquette? Is this behavior as bad as I think it is? WTF?
