I am not printing your letter for your protection.
I hope you have a password. Writing to me on a computer your husband has access to is very, very dangerous. Please delete the history in your computer and only use a library computer for this type of mail.
You need to call the Domestic Violence hotline at 1-800-799-SAFE (7233). There are people there 24/7 who can help you figure out what you need to do and how. Please call them as soon as you are in a safe place to do so.
You are definitely in danger. You owe it to your children and yourself to get out of the situation as quickly as you can.
I wish you well.
