My hest friend is 15 and she's dating this 19 year old guy she ditches class with him and they've started having sex and she juat texted me twlling me that she's at his house and really sketched out by him and his friend and is scared and i dont know what to do to help her but there isnt anyone with a car who can drive up there to help her right now and i dont know what to do

Edit: her brother helped her out and she's safe now but it turns out she was given meth while she was there and the guy is in alot of trouble now
