My friend is single (separated) and has been having an emotional affair with a man for over 3 years.
He is married with 4 daughters.
Nothing physical has happened. He lives miles away (they met at work) and they have agreed never to meet up.
They Facebook message each other, talk on the phone every day and texts.
She refuses to believe there is any problem with this as she hasn't shagged him.
I've told her that I feel uncomfortable about it but she keeps looking for my approval.
I have run out of things to say.
