They are not people to harm physically (no need for the police) but they have messed with my head by manipulating my life in such a way that I am almost destroyed. Yet this has not been done with intent, but by their sheer self-absorption. They believe they are victims, and have used my over-sensitivity and kind manner to their own ends, which is why I am reluctant to send a message, as I have not had contact with them for a long time.

I think Anita was right to say in a perfect world to send a sympathy, saying I want no further contact. I just feel this is going to be difficult to do without making them angry and more upset at a difficult time, so may have to leave it. Thank you for your answers.
