My DD has been invited to birthday party sleepover for very good friend who is a boy turning aged 9. They’ve been friends for years and I am good friends with his mum. However my DD will be the only girl there amongst 4/5 boys. AIBU to feel a bit unsure about this? I was sexually assaulted by a boy when I was 7 , who was also same age as me...perhaps this is fuelling my anxiety. My daughter really wants to go. WWYD?
