Was in set and met this cute girl. Got her number and exchange laughter and good times.

As I was walking this way, this guy stopped me and told me I was being creepy. Asked me stuff like, “Do you have sisters? A mother?” etc….

He told me he was going to go to the girl and get my name from her and report me to the police.

I just brushed it off and walked on.

Tried texting the girl later and turns out she blocked me.

Kinda bummed me out since it was a successful interaction. Looking for advice at how to handle these type of white knight dudes.
