What did I do?

This actually happened a few months ago but this is about the last time I went on a traditional date. 

I met this guy online. He was my age, hispanic, calm natured, my height, my weight, and super cute. We talked a bit online and liked each other enough to meet for dinner. We met at the Olive Garden off of the Beltway and 45. Just like his pictures, he was sooo cute, we even dressed similarly, so off course, in my mind, I was screaming "YESSS!!!" But...no

He was quiet most of the time, I found myself talking mostly just to end the silence. He explained he was shy and tired. I believed it, so I tried to bring smiles and laughs only to have half smiles, no eye contact, and forced laughs. He began to rush out of dinner, asking for the check when asked about desert and looking antsy to leave. We left, I of course paid for dinner and he ended with a firm and thank you hand shake. 

He didn't answer my call (singular) or any of my texts (plural), even the ones where I admitted to understanding he wasn't into me but I'd like to maybe be friends since it was rare for me to find another gay guy who was as calm natured and conservative as I was. But...

Never heard from him again.

The logical side of me understands that this is typical dating, and that it happens all the time, and I can't get rung up over one bad date when the city is probably full of guys I'd like, I just haven't found them yet...but the other side asks..."What did I do?"
