Please say nothing to him today. Like Mr. Bond said you will be signing the D yourself.
Can you and your son sleep at a friends or families house tonight? trust me your prespective will change if you wait a day or a week or two. Even if you feel them same you will not speak with such anger.
What are the results you want? Do you want your H to come back to your marriage?
If you tell your H off, you are pushing him farther away from you. It will reinforce his thoughts about you
