That is a risk, Esmay, but I'm sure you come across as a very lovely person so she must have felt very safe with you. Those are serious secrets.
I have kept other secrets too, but the ones my friend told me are not like anything I've heard before. I wish I could not know. There is no one to tell now. I didn't ever get to know the kids, though they've got in touch to ask me if I knew anything about the cause of the suicide (I don't) It's kinder if they don't know who their parent was, so I'll never tell but just hope for their sakes that they never find evidence when clearing the house.
