One, the song was pretty good, well played and sung and performed, nice enough melody, rhythm etc..
Two, it was so maudlin and mawkish.
It sort of is a sad song. But there is also a message of hope and empowerment and, to some degree, conservatism. She wants to take care of her drunk dad who gave up on life. She dreams of leaving to pursue a better life. They work hard and want to achieve and eventually climb out of the hole. Her husband ends up being neglectful of the family (they say women marry their fathers!) and she asks him to leave because it’s a cycle of destruction she cannot allow to repeat.
My interpretation. But it’s pretty plain by the lyrics.
