None of this is YOUR fault. Your S is making bad choices, and the truth of the matter honey is that YOU CAN'T MAKE HIM CHOOSE DIFFERENTLY.
Let him feel and take the consequences. The worst thing you can do is save him from his choices. Will it hurt? Yes. But it's through our hurts and failures that we have the opportunity to learn.
Have you told his PO about the threats he's made to you? I would...because telling your mother that you're going to wait until she's asleep then cover her with gasoline and set her on fire is NOT in the normal range OR okay.
You're going to have to be strong...this is DBing at its best. Don't show your crying or weakness to your S because it feeds into his manipulation.
What are you doing to take care of yourself during this time?
