I think he would be mortified to think he was a rapist.
Then mortify him. He needs a massive shock to the system so that he does not repeat, repeat, repeat. It is not your job to bring him to account. But I would urge you to consider going to the police also. If not you, he seriously wants to hurt someone.
I’m not worried about the kids being poor I’m worried if they will be hungry and cold.
I have been hungry and cold before. As a kid, and as a 20 year old and as an adult. It builds your character. I would be more worried about being ripped apart by a tiger than my kids freezing to death. Your kids won't starve and they won't freeze to death.
And the tiger won't come near you. It is just a myth.
Who told you that your kids will be hungry and cold?

I am a father and I worry about the future. I worry that society is becoming more misogynist. Not less. I will have no problem with my daughters, but I fear for the rest of my time I shall be fighting a rearguard action to deflect my sons from being sucked into the sexist shit that the internet can deliver to them on a plate.
