This is a song about a man who has taken his wife or girlfriend for granted. He isn’t abusive, but isn’t present. He has become comfortable in her being there without realizing she needs to be loved by more than just filling a room with his presence. He doesn’t realize why she left until she’s gone. He had become so self absorbed in his work or self he, like many others, ignored the signs and her. She became tired of being ignored or made to feel like his maid or mother. She wanted and needed someone to love and to love her back. She felt invisible.
