Sherrine, AustenFan, Statgeek, Donnaeil and Dagger: Thank you all so very much for you much needed and excellent advice.
Yesterday I went to the Police and filed a complaint against my ex, the Police said it was harassment but as he has not broken any laws yet all they can do is speak to him and warn him off.
He found out where we live by tricking a friend into thinking that he knew where we were, she, in all innocense said oh yes (name of road) is a lovely area, she did not tell him the number of my house, so his intention yesterday was to drive around until he saw my car.
I have informed my solicitor, who is going to write to write a warning letter to him.
I am now thinking it is time to write to his employers and inform them of what he is doing, he has a good career and woould be frightened of them finding out what he really is, so i'm going to write the letter today, wish me luck and watch this space!
Thank you all for your support.
