Why did he ghosted me when firstly seems so interested?

Can't get over a guy who ghosted me out of the blue after been talking with me one week. He wanted to have sex the day we met at the club, but then I texted him and he talked about a week. I went on vacations and told him when I came back we would schedule something and he said I'll be waiting. so I texted him when I came back and he never replied anymore. driving insane with this 😭. Should I text him. again?
