Thanks for all your answers guys. She hasn't changed her number because she's had it for 15 years and too many people know her to change. And, of course, why should she.
Im going to try to talk to her tonight to see what she's done about it. If a complaint is made, im pretty sure the police will have to act on it....it's just whether this will make things worse as he knows where she lives.
She's a bloody nice girl and really doesn't want to rock the boat by telling his wife and if she blocked his number, he'd buy a new pay as you go cheapy phone for a tenner.
I'll let you know the outcome.
Thanks again
