My second husband abused my two small sons from my first marriage. Not in a sexual way, but he was very cruel to them. I had to leave, of course, and he attempted to have me sectioned, saying I was an unfit parent who could not administer 'wholesome discipline'.
He was unsuccessful, and I tried to get on with my life, taking a job as a nursing sister at a hospital some distance from him.
He wasn't going to give in, and wrote to the Matron telling her that I was a criminal, involved in prostitution and doing back street abortions.
The police warned him off, but all my alleged 'misdeeds' naturally had to be investigated as I was in a position of trust. Thankfully my colleagues and managers were amazingly and unflaggingly supportive, and I came through it all, but I can't describe the anguish I suffered.
I still have nightmares about that man, and though he died some years ago , I can NEVER forgive or forget, and sometimes wish he was still alive so that I could kill him slowly and painfully!
