i have a 14th reason, it does damage to the kid also - there are some females that uses a good man especially when he is a good man and a great potiential father. the woman uses that to her advantage and gets what she want and when the good man has grown to love her child like his own and that child grown attach to the step father like her real fater, when things doent work out with the mother the mother will ses her child to sill have you around and when that child hasn't seen you anymore it does damage to the child's mind and sees how his or her other is and winds up thinking thats how relationships suppost to be. child loses stubbility in a father role model and takes a long time for the childto get use to not having the step father there no more especially in some cases it was the mother's fault because she still wants to act like a tricking hoe and doing scandlious things.
