Why are statistics against men?

when it comes to parenthood, every women seems to think that the man is the least important in the kids life. its funny how women seem to change after a kids is born for the worst. they call it for the better. but reality the change they made actually made it more intolerable for men to stay. what man wants his lady to view him as not important when it comes to the kids. what about family values with out women saying "My Child" all the time leaving the man out. my question is for the ladies why do most not all but most women act this way. dont you see the fact that this way of thinking destroys families.
