Personal relationships are what they are. The power play between participants is a dynamic & politics that can't be readily understood by those outside it.
PLUS hyperbole and extremity are part of the art of expressing all relationships.
I co-wrote a non gender specific love song back in 85 or so for a musical. it worked well and, in fact, I don't think many who saw the show actually noticed.
That song was about the powerplay as much as the love play.
Your song essay the imbalance and resignation to it - I think that's fine - good even.
As a song...mate, your voice, that melody and arrangement... you could easily be singing the alphabet & it'd work. As it stands the narrative is cool & everything gels for a fab track.
