We've known each other since preschool and I care about her. She's the closest to me out of all of my friends. I have always kept her safe in the past. She has always had a habit of doing dangerous things. Right now she refuses to speak to me, because yesterday I stopped her from meeting a guy she had met on Facebook at his place. She's 16 years old and was trying to meet this guy who was in his late 20s. This is the second time she has tried this and I keep warning her that's it's very dangerous but she won't listen to me.
Earlier this week, she tried to get me to sneak out to this party with her, but I told her no. She text me that she went without me, so I called her housephone and told her mom. I didn't want her to go because last week we went to a party and she got drunk and I got stuck driving her illegally (I'm 15 years old and I don't have a permit) back to her house. I'm not trying to be a buzzkill, I just don't want to her to get hurt or worse. Do any of you have advice on what i should do?
