Why has he ghosted..

So me and a guy have been talking nearly 2 months, we even went on holiday together. He told me he sees a future etc he likes where things are heading. Even our families know about it. Suddenly last week our messages weren’t as much but he said he was super stressed and busy. I gave him the benefit of the doubt. Suddenly since Friday evening he’s just ghosted me.. like nothing what do ever. Why? Why do guys do this.. he claims to be so straight up but clearly not..

He’s been online on WhatsApp he’s been on his socials he’s just blatantly ignoring me..
