I think he is right about natural consequences. You reporting him is not natural. It is an attempt at manipulation - telling him that you have power over him and threatening to use it. I don't mean to be mean and I hope it doesn;t come across that way - I am just giving you my analysis of what you're doing.
And from my own marriage, what happens next is that he calls you a controlling witch and tells you to worry about your own problems and let him worry about his, and ultimately he is right. Worry about YOU.
Unless he is hurting you, I would not take a step that causes him to lose his job. I would file for temporary child support while the case is pending and while he is still working - not do something that threatens your livelihood. That wouldn't be smart.
