Say, a guy Tom lives with his family. He is completely ignored by others at home. His wife harasses his kid and if he says something, his wife just says rubbish. Whatever others want, they do without Tom's consent. If Tom interferes on wrong things & comes in their way to stop the wrong, he is manhandled. So, others can do whatever they want and he can't do anything to stop them. Whenever others want to harass his kid, they do and later Tom, who cares a lot for the well being of kid, salves her (the kid). So Tom does everything for the happiness of the kid from his side but can't stop others of their hooliganism. He is just brushed aside.
What word can be used for him to signify his status at home?
