Cheating on your partner is bad enough, but cheating on your partner with someone you thought was your friend, or your best friend, even, is worse.

CAVEAT: I know some women will call friends, regardless of gender, "Love, Darling," or whatever, just to be friendly. I had a girlfriend of sorts,, who, when a sales assistant called me "Honey" she accused me of cheating because I didn't tell her not to. Similarly, an innocent, social kiss on the cheek cannot, in my view, be regarded as cheating. Say, for instance, you go to your husband's school reunion and an old female classmate gives him a kiss on the cheek, or a hug, that is not cheating, either.

If, however, a woman who another woman thought was her friend, likes her husband, and they are having an extramarital affair, you have to ask several questions. One, is she only her friend because she wants to see her husband? And is she really her friend?

This is also where the ridiculous doctor who claims that men and women can never be just friends is pulled apart. Let's assume a woman does have eyes for another woman's husband, would the relationship be saved if they terminated the friendship? Probably not, because each would have eyes for another. And, contrary to what this ridiculous doctor claimed, it is not about women supporting each other.

Men and women can be friends, but what we need to consider is this, with polyamory becoming more socially acceptable, if one partner is monogamous and one is not, have they married the right people? To me, the answer is no.
