You need to see a lawyer and protect yourself. You also need to seek legal advice regarding his forged documents, especially now that you know about it. You might have some liability to report it.
No one can tell YOU what to do, but if I were in your position, I'd get legal advice asap, separate myself from this man permanently, and I'd even consider pressing charges against him and reporting the forged documents, all after seeking legal advice, of course.
So sorry you are going through this. He doesn't deserve another dime, or you.
