DD has a small friend group of 5 girls including her, and 1 boy. They're all 16/17 but the boy in question is 16, let's call him C.
They all went to one of the girls houses yesterday including DDs boyfriend. They were drinking but weren't drunk according to DD. Today, she told me C was kissing the her friends and then tried to kiss DD, she told him no but he kissed her anyway. Her bf confronted him and he said it was a joke and caused an argument and was playing the victim.
The girls who's house it was told DD and her bf to leave as bf was winding C up, one of the girls agreed with DD and her bf but the rest agreed with C that it was a joke
AIBU in thinking that this isn't a joke? And wibu to tell his mum or wouldn't you at their ages?
