Hello hadit and little imp,
I thank you both for your kind words it has helped me to help my sister a lot. It was hard to know whether to post this horrible event or not I do feel some how disloyal to my mother, but it was my sister I was thinking of and it is my sister life that has been damaged by this. I have read out all your comments to my sister (she has no access to a computer) and slowly she is starting to realize that it is not her fault.
I'm sure that your husband when he feels that the time is right will post his story here, he will receive only love and support like my sister has, which helps to heal.
