I have some thoughts on this topic.
First of all, let me say that I define 'fidelity' as not cheating on your romantic partner and not knowingly cheating with someone who has a romantic partner even if you yourself are single.
I define 'romantic partner' as anyone with whom your are in a relationship in which there is an explicit understanding that it is exclusive OR in which there is a reasonably understood implicit expectation of monogamy. To me this is not contingent upon any sort of legal status or any sort of ceremony the individuals have made. Violating such things may be 'worse' if you want to think about it that way, but it's still 'cheating' regardless of any legality or ceremony if there is a violation of an explicit or implicit expectation of monogamy.

In politics a decade ago, if you were caught in bed with someone that you are not married to, then you get royally roasted by the press in countries.
First off, I think that the original post in this thread is hitting quite a few different points which I personally think are unrelated to monogamy. For example the above may only apply to 'fornication', or having sex outside of marriage. Honestly, I don't consider that a moral wrong or a 'misdemeanor'; that's completely up to the two (or more) individuals involved and I attach no moral or social judgment to it.
The 'cheating' is what is wrong, what consenting, unattached adults do in their private lives is perfectly acceptable as far as I'm concerned.

Today, things seem alittle different and almost half-expected/half-jokingly from politicians to have a half a dozen affairs. John Edwards, who could have been the vice-president, is now under heat for the exact problem over his infidelity. Eliot spitzer is another in a row of politicians with an interest in hookers.
This issue transcends sexuality and parties as we have seen with Senator Craig of the Republicans.
Now we're talking about politics? OK, fair enough since this is the soapbox, but I was expecting a topic that was merely controversial on moral/social issues not one about politics. Personally, I prefer to keep it out of politics, because it's more interesting without tying it to politics (or religion), but since you brought it up here's my brief opinion about it politically:
I couldn't care less. I think that cheating is a very serious moral wrong, but just because someone commits a 'moral wrong' in one area of their lives is, as far as I'm concerned, irrelevant to the other areas. I would be upset if my minister or other religious leader committed adultery. I would be upset if someone cheated on a friend or family member. I do not care,
at all, who a politician, actor, athlete, or other celebrity sleeps with. Nor do I care whether or not my taxi driver, cashier, fireman, or hairstylist is having an affair. As long as they can make policy decisions, get their lines right, keep their eye on the ball, sing properly, stay inside the lanes, make correct change, spray the blaze, or get my highlights right I really DON'T CARE.

I do not have the answers, but it is an odd dichotomy if you look at it. People say they hate infideity, but most water cooler talk or stories among men usually revolve around how hot some one is or their personal desire to seek a sexual exchange with them.
That also seems off-topic to me. That's more or less dealing with gossip and plain old lust. I don't consider these to equate to infidelity either. I personally don't think it's inappropriate for someone in a relationship to
lust after someone else, particularly in the casual, checking them out, brief fantasy way. It would be more problematic if they actually became
fixated on the person, but if it's just thinking "WOW! He/she is hot! I'd like to bang them." Well whatever, that's just human nature and that's not, in my opinion, being disloyal to your partner. I'll throw in that nor is pornography as far as I'm concerned. It's what people actually
do that matters.
Now that that's covered, I think that infidelity is
awful. I think it's one of the worst things a person can do. It's definitely a 'moral wrong' and a very serious one. I would never tolerate infidelity in my relationships.
However, I would be very clear about my expectations. I would let my partner know how serious I think this is and I would explicitly tell him that I WILL NOT tolerate it and that the relationship WILL be over if he cheats. I have a similar policy on verbal, physical, and emotional abuse. I'm not tolerating it and if it happens, well don't let the door hit you on your way out.
That said, I don't have any problem at all with 'open relationships'. It's not how I would be likely to conduct
my own relationship, precisely because monogamy is important to me, but if it works for other people than more power to them. Furthermore, if it really does work for them, then I wouldn't feel bad about messing around with one or both of them. I wouldn't get involved in any long-term sexual relationship with either because I think that could get too complicated, but it's their relationship not mine, and as long as they're playing by the rules and happy then I don't care either.
I would be perfectly willing to date someone who had previously been in open relationships. I would be very hesitant to date someone who had cheated in a monogamous relationship. To me it's all about playing by the rules in the relationship in which you're in. The open relationship person wasn't doing anything wrong (IMO) and there's no evidence that he can't play by the rules of a monogamous relationship. The person who cheated on the other hand DID do something wrong and there IS evidence that he has trouble playing by the rules of his relationship. So all things being equal I'd definitely trust 'open relationship guy' more to be fateful.
Do I make exceptions for sexuality or 'true love'? Hell no! Sorry if that sounds harsh but if you're in a monogamous relationship with someone of the 'wrong gender' or if you suddenly meet your 'real' true love. Well tough! You can either deal with the consequences of your past decision to enter your present relationship and do nothing OR you can leave your current relationship and pursue the person you're interested in. But that
does not give you a right to violate the terms of your current relationship just because 'something better came along'.
Of course that opinion is highly biased by my own preference. I would
much rather be broken up with than cheated on. I would
respect someone who was man enough to tell me he was in love with someone else, or simply that he didn't think our relationship was working for him anymore. I could imagine still liking that person and maintaining a friendship with him afterward. If I'm cheated on then frankly I lose all respect and trust for that person and while I would definitely expect to forgive him, I doubt I'd want him in my life anymore, even as a friend and that goes back to trust, honesty, and betrayal.
Anyway, addressing the other points in this thread, I don't think what heterosexual society deems appropriate should have any bearing on gay relationships. Of course I don't think it should have any bearing on
straight relationships either. Who cares what society thinks is appropriate? I don't live my life to satisfy 'society' and I don't expect anyone else to either. Morality is far more complicated than what 'society' pushes down people's throats. It's up to individuals to establish their own system of morality and their own concepts of right and wrong. Those ethics, IMO, should be based on the simple premise of not doing harm to others or to oneself. The 'Golden Rule' really makes a lot of sense. I'm not going to consider something 'moral' or 'immoral' simply because
society deems it so; I'm going to work it out for myself.
Anyway, as far as relationships go, it's definitely important for the individuals involved to work out how they want their relationship to work and what they expect. It's fine if they don't want and expect what I want and expect. All that matters is that they want and expect the same things and that they stick to them.
So that's my opinion of infidelity

Take care all and have a great day!
