Wow....thank you for the compliment, minnie. I'm glad if I had an impact on you making a potentially bad decision.
I know a number of people, men and women, who've been involved in these kinds of situations, and it always involves deception (including self-deception) and it always ends badly. Even those women who say "I'm only in it for the sex," seem to be hit pretty hard emotionally when it ends.
I also think it's just generally not good to cultivate the feeling that we have no responsibility towards other human beings, even those we haven't met. The other women I've known have all taken the attitude that they would not tolerate a husband of theirs cheating on them -- that it would be terrible and hurtful -- but they have no problem contributing to that hurt for someone else. The "I don't know her, I don't owe her anything" defense. If everyone applied that kind of thinking throughout their lives, the blood banks would be empty. I think women need to stand up and be counted for and do unto others as you would have them do unto you. Walk a mile in her shoes before you make the decision to get entwined in her life.
Thats my theory, anyway, and I'm sticking to it.
