A father/husband is the head of the family. He is the main provider for the family. But there is a lot more expected from him aside from being a good provider. He is expected to love, cherish and protect each of the member of the family. Decisions within the family are mostly not made if not through him or with him. One of the most important thing he can give to his family is spending quality time with them. Make your family feel that you care for them by making sure that you dont miss out on what's happenning to them on a day to day basis.
He can do it by following sincerity,equality and love.
