You might try a search for "triad" "triads" in the tags. There ar quite a few threads that might help you determined a course of action for you. Again, if you are not in love with this woman I'm not sure why the instance of a triad. It seems common for couples to take on thee most difficult poly structure. I'm not sure why, but perhaps some light will be shed on why its difficult if you read a bit.
Actually, come to think of it, I do have an idea of why... I think couples think that love is always the same between people. That its balanced and even. Actually it isn't. Its different for everyone involved. Your love for him will be different than for her and his love for you will be different than with her.
