A deadbeat dad is a man who does not provide financial support for his offspring or spend any quality time with the children. This term is a derogatory way of saying that the father is not living up to his responsibilities, and that he created children but is not man enough to take care of them and provide what they need to survive and succeed in this world.
Anything that costs you your peace is too expensive let it go.
A deadbeat thinks of the person in the mirror, not the child in the shadow.
