Well, Ladies and Gentlemen, I did it. I went to the County Sheriff's Office and filed a complaint against OW for identity theft and fraud. They took down my complaint and faxed it over to the Prosecuting Attorney, who has ordered a complete background check.
I fought with myself over whether or not to do this, and came up with, If someone I didn't know had done this, even if my husband was living at home and she knew neither of us, would I let her get away with it? Nope.
I guess I better get back out and start digging my moat. Maybe put some crocodiles and sea serpents in it just for protection sake.
