I went through divorce six years ago, initiated by my wife while I was in a medical crisis.
I took the attitude “I am sick, let her have the $$$ she wants and I will use my energy to fight illness.” In a way, I had little choice due to my condition. I had to give up control.
In the end, my backing down allowed us to actually talk and things ended up relatively fairly. We have a daughter together and she is living with her Mom for a year, and this came about through an amiable discussion. The financial issues also were resolved, in the end, in a fair manner.
My point? The harder you fight, the harder he will fight, and more damage of all kinds will occur. The marriage is over, take the high road as best you can and that will make the future of your kids much easier. Don’t squabble over money. Hating each other over money is toxic.
I am healthy and re-married, and my bank account has more than recovered. I hope you also have such good luck ahead.
I am very sorry for the pain you are going through in divorce.
