Divorce is not the end of the world. However, it's often the end of most dad's major bonding and influence with his kids. Most divorces end with dads being marginalized by the family court precedents.
I walk away from this story knowing I did everything I could to keep the marriage alive. And after the divorce, I've done everything I can (outside of shutting down my writing) to be a good father, a good man, and a reasonable person.
In the final settlement, I got something called the Standard Possession Order, which amounts to a split of time that works out to 30% for the dad, 70% for the mom. I was losing 2/3 of my time with you and your brother. My biggest fear was coming true.
You can't have kids by yourself. Your partner is just as important. Why would it be different when you no longer live together?
Parenting is a spiritual journey that you enter when your kids are born. The relationships you have as parents may change over time, but your parenting is a huge part of what gives your life meaning. To me, my kids are everything. And to my partner, my love of their kids and their love of my kids, is unfathomable and wonderful when it happens.
Release the relationships that are not meeting your basic conditions of satisfaction. And nourish and build relationships that build warm and fuzzy connections.
I am lovable just as I am. I am lovable with brown hair or grey hair. I am loved at my current weight and even when I'm heavier. I am loved just as I am. I am not sure I believe all of what I just wrote, but I'm on my own journey to get there.
But, when the parter continues to shut down or respond in unhealthy and indifferent ways and refuses to own their side of the problem, it might be time for some serious reconsideration.
