I just today realized that the song "Two Lovers" (by Mary Wells) is about an abusive relationship.

"Two Lovers"


Well, i've got two lovers and i ain't ashamed
two lovers, and i love them both the same
Let me tell you 'bout my first lover:
he's sweet and kind and he's mine, all mine
he treats me good like a lover should
and makes me love him
i really really love him
wo wo oh (wo oh)
i love him so (love him so)
and i'll do everything i can to let him know

Well, i've got two lovers and i ain't ashamed
two lovers, and i love them both the same
Let me tell you 'bout my other lover:
you know, he treats me bad, makes me sad
makes be cry, but still i can't deny
that i love him
i really really love him
wo wo oh (wo oh)
i love him so (love him so)
and i'll do everything i can to let him know

Darling, well
don't you know that i can tell
whenever i look at you
that you think that i'm untrue
'cause i say that i love two
but i really really do
'cause you're a split personality (personality)
and in reality (reality)
both of them are you (they both are you)

Well, i've got two lovers and i ain't ashamed
two lovers, and i love them both the same
two lovers, and i ain't ashamed...
