frumnotyeshivish,
actually I think that who is the initiator of a no-fault divorce has a alot of bearing in arranging child custody.
You see children are way better off on so many levels and in so many ways growing up in a home with both biological parents.
If a woman initiates the destruction of that home for selfish reasons and in spite of the husbands obvious willingness to work on things and keep things together so theat their children will not have to grow up in two homes and in two worlds.
Well I would think thats the first sign that perhaps the mother is not really the best person to be raising those kids.
