although I 'd like to say it all boils down to respect...thats an emotion that so many people today do not place any importance upon..
I never said not respecting anyone else's relationship was the right thing to do, but in answer to the question, I have to say that it is the responsibility of the committed person to ultimately respect their spouse enough not to cheat and to honour their relationship...we are by nature, predators, it's a basic instinct..so some of us prey on others, and some of us do not stop to think if it is right or wrong...
then again, if you are in a relationship, and another woman/man, not your spouse, decided they wanted you, all you have to do is say NO....then there is no problem, no cheating..in other words you have repected your relationship to the point where you could walk away and not let yourself be tempted...
I never said, "do unto others before they do unto you"..the question was whether you have a responsibility to respect anothers relationship, not whether you think it is morally right or wrong to have sexual relations with a person who has a spouse already...
and Kem, while my statements may sound selfish, they are certainly not narsissistic, I was not only thinking of myself, I was merely placing the responsibility where it should be placed, in the hands of the one who is committed...if we each look after our own..no problem!!!
