What the fuck just happened……

I was talking to this guy for about 10 days, and our conversations were really good. It seemed like he was genuinely interested; he would call me first thing in the morning and text me throughout the day. He asked about my past and what I was doing every day. Then, one morning, he suddenly blocked me on every platform—completely cutting off all communication. Now I'm just so confused about what happened. What the heck?

Why did this happened ??
