My DN has messaged me to say that my 14 YO DD is in a group with two school friends and one of the school friends has introduced a guy into it that none of them know who says he is 20 and is going through a break up with his girlfriend. My DD is suspicious of this guy and wants her friends to start another group that does not involve this guy but her friends don't want to do this. I obviously need to talk to my daughter about this but my DN has asked I do not let my DD know she has told me. I am not sure how to broach this now without betraying the confidence of my DN, I also (and more importantly) don't know the right avenues of dealing with the guy who thinks its ok to approach three 14 YO girls. If indeed he is even 20 YO and who he says he is. If there is anything more sinister to this I don't want him to be able to go off and join another group of girls. Does anyone have any advice? Many thanks for reading
