(((Distressed)) - In my honest opinion I don't think you should send him this letter. At the moment, your emotions are all too raw right now. A man who does this to his own sister in law, not to mention you were a child, doesn't have the compassion or common sense of a normal human being to absorb or comprehend what you would say in the letter - in other words you're more of a human than he is.

To talk about forgiveness for him at this point, is way too soon IMO because he's totally denying he did this and being abusive to you. He also abuses your sister and I'm sorry to say he's a disgusting person - you can't make common sense to this kind of man.

Completely block him from your email. I'm not saying that at some point you can find forgiveness, but not now when everything is so fired up. I think it would be a big mistake to send it. Forgiving him at this point would be making it so easy for him. Be patient and don't make any decisions - you're too upset to think logically. I think you should speak to your therapist - my heart goes out to you.
