I do hail from a broken family as you put it and I'm darn proud of my past.
You were brought up by your mother, and I can sense a strong bias in favor of the females as a result of that.
I think most women get the custody because in most cases the father is the major bread earner and he need to keep his job and focus on that so he can continue to pay for his kids.
Do you think that the males are some sort of machines without any emotion, who should work till they die to feed gold-diggers? Also, in your country what is the work participation rate of the females?
In my country, I have seen countless examples of gold diggers winning custody of the children and then using their rights to prevent the fathers from even communicating with their children. And they don't work, as the alimony and child support payment is enough to sponsor their luxurious lifestyle.
