DD has a friend over for a sleepover (they are 11) I don't know the friends mum very well and not met the dad yet.
Just heard DDs friend tell DD she has read messages on her dads phone (she plays games on it) to another women.
Things like, morning gorgeous, I love the dress you had on today, told wife I'm working till 10pm so see you at yours for 8pm etc
DD said she should tell her mum but friend said no because she didn't want them to divorce 
Wwyd?
