Thanks for your reply.
People are free to say what they like to other people provided that what they say must not be defamatory. In order to be defamatory (ie. Libel or slander), it must:-
- 1. Be a false statement
- 2. Communicated publicly (ie. To another person other than the defamor and the defamed
- 3. Cause damage to the person who is defamed.
We're in tricky territory with your situation if all she is doing is repeating what she said to you or suggesting that you your comment was made with a view to suggesting that he marriage was fragile because neither is technically making a false statement. Were there other false statements made then you could in theory have an action against her.
However defamation actions are extremely expensive (tens of thousands of pounds in legal fees - no legal aid), with a unpredictable degree of success and it is only worth suing a person if they have money against which you could enforce judgement.
The police will not be interested in this obviously, it is a civil matter.
I would attempt to resolves the situation informally and appeal her sense that any comment you made was simply out of wish to support her.
If you cannot resolves your dispute informally with her then you may consider asking a solicitor to write a letter before action to her asking her not to repeat false statements but she will probably know that the expense of a defamation action is prohibitive and so it may inflame the situation.
Sorry it could not be better news, I'm sure it's frustrating.
