Hi Rouky. This is my first time writing to you. I´m really sad you are feeling this way now. I can see you are suffering. Your kids are suffering, surely your EX is suffering. Let me tell you, from a former WH myself, there´s sadness on the other side too. But as time goes by, you know it´s not always like this, right?
We live in a real world. There´s injustice everywhere. So it´s up to us the way we choose to live. Sometimes our reality is very unfair, but it is ours, we can change it. It´s not easy but what else can we do? Just take the wins into account but not forgeting the losses as we learn from them. Willingness to do something requires energy. Use that negative energy you are getting sometimes to grow yourself, to improve and become a better person.
You can be proud of yourself, your kids are seeing you as a role model. You are there for them, you are the caretaker, you are the lighthouse. Your kids will always love their father too, even if they do not understand him. But they know who to trust: you.
