Dear Paul.
I am really sorry to hear that the thing you married is divorcing you and trying to screw you for some of your money. I don't think that she should be able to do this. I actually like you and I think that you are a nice person and an excellent singer/songwriter. I wouldn't give her a penny as all of the lies she has said about you must have been really upsetting. At least she's representing herself, her lawyer has a fool for a client.
I wish you well, you've had a lucky escape and now you can move on with your life.
Best wishes.
