Throughout the marriage he cheated on her - (with a stripper and others) which exposes her to some deadly diseases. (HIV, stds that cause cancer) which effects the children because it makes them at risk for having a sick mom or shortening the life of their mom.
He depleted family funds on gambling, addictions, partying with his friends while she was home taking care of the kids.
He emotionally abused her (which is psychologically damaging for years)
And even now continues to gaslight by making her look like the villain in front of the kids.
I dont hear remorse at how he hurt her amd the kids. Only how she no longer is giving him what he needs. Thats what he is remorseful for.
Infocus, what can you do that is selfless for your family? Financially? Physically regarding housework and care for the kids? How can you make it about them and not you?
