Yes, kids are expensive, but they should be equally shared as an expense and as a joy. This 70/30 split is bullshit. It's demeaning to fathers. And it's based on a parenting concept from the 50's. Sure it makes it easier on the courts if everyone just goes with the plan. But don't. If you want the time with your kids, fight for it.
I loved the family routine. I loved being their dad. I knew I was going to crash when I was no longer welcome in my own home. I knew depression was weeks away. I knew there was very little I could do to stop the sadness freight train that is divorce.
It was not fair what happened, and in many ways, my ex-wife was the architect and builder of the divorce.
Today, the law serves the best interest of the kids and the mom. Dad is seen as the breadwinner, and thus the "paycheck" for divorcing moms who are showed the divorce brochure and the good deal they are being offered.
We could've separated and agreed to a 50/50 parenting and 50/50 custody schedule as I requested. That was more in keeping with the way we parented. But it did not match up with my then-wife's objectives. Those "options" she learned about from the attorney, rather than the options about staying in the relationship she could've learned in the couple's therapy.
