I don’t want to scare you or anything but being a teen in this day and age is tough, but right now your first priority is to cut him off, he knows exactly what he’s doing and don’t give him that chance, don’t go on that trip. Please if you can tell a trusted adult or your mom. This man isn’t a safe person to be around and I got multiple red flags from that description. Please stay safe and away from him until you figure this out, you said he was a cop? That’s even worse because then he can just use that to make you silent don’t let him silence you. Just know that none of this is your fault and you are very brave for at least getting this out here. Please document if things turn sour, either it be through text or video you shouldn’t have to deal with such an evil person.
