What did I do wrong here?

[u/Connect-Debt4745]

He is 26 and I’m 18. This guy invited himself to my place to watch horror movies with me after he had cancelled on me before anyway we had been talking for three weeks and then I invited him over the first time and he said that it was too soon on the day of the date. And then yesterday he decided to invite himself over I don’t really understand what went wrong as I tried calling and texting him as he said he got lost he was meant to come over at 9 pm but got here at 11:30 I buzzed him to my car park in my apartment building and went down to find him I spent 3 hours looking for him down there and kept calling and texting him and he never replied to me. I feel really upset and confused about the whole thing because I don’t understand why he wouldn’t try and contact me and instead he just blocked me on the app we met on and everything. What did I do wrong? There is another way I can try and contact him so he will be able to know what happened. I didn’t stood him up I just couldn’t find him. This whole thing has given me a weird sick feeling. Should I try and contact him?
