I feel for this guy. My first wife and I divorced, after years of her infidelity. I remarried, and the children liked my second wife. From her jealousy of my second wife she concocted false charges of child abuse. After tens of thousands in legal costs, I was done.
I have not seen my oldest son and daughter for 7 years.
The good news: If I can hold on, after 10 years the kids usually are free enough of the mom's brainwashing so that I will have a relationship with them then.
At least we can understand what the hell you are trying to say!
