Guy blocked me day of second date.

I am really confused here and this whole situation has left me feeling like a POS. I went on a date with a guy about a week ago and we had a GREAT time. I mean we had amazing chemistry and talked the whole time. We kissed at the end and agreed to see each other again. He kept boasting about how cool he thought I was. A few days later i hit him up and asked if he wanted to go with me to get a piercing and make a day out of it, he agreed. Over the next couple days before our date (today) he got super dry, but i assumed he was just working (He does HVAC). Yesterday i messaged him asking if we were still on for today. No response. And today im blocked! I dont really understand why. This is the second guy who has ghosted me and im starting to feel like maybe im just a weirdo or something.
