Dear Tony,

I am a gay male who recently ended a 17 year relationship with my partner because he is confused.  Now we are those down low types you hear about.  We look, act, dress and live as straight men, however are very much gay.  Since the breakup I have learned that my former
partner is sleeping with his daughter's mother, who by the way has been married about 5 years and I believe her husband doesn't suspect anything.  When I met him his child was about 10 years old.  I never understood how this woman could maintain feelings for a man that she knows is gay and living with a male partner.  I frequently see these people, husband included and want to tell him.

Am I wrong?
