Why are you so certain is the woman’s fault? No woman will intentionally leave the father of her children out unless he did something to warrant that action.
Why aren't the fathers fighting for their rights if they so want to be in the child's life? Or do you expect women to take back men who abandoned them simply because he realized he wants to be a father after years of not paying child's support?
We need to stop blaming only mothers for the way child turn out. Beside we have children raised by both parent who wish they had never been born.
We should stop this habit of guilt tripping women for any bad thing in the relationship. Just like we have horrible father, there are horrible mothers too. So enough of the projection on mothers.
