Do the members of a married couple with children have a moral obligation, not (just) to each other, but to their children, to not cheat on each other?

I'm guessing what the questioner is wondering is roughly this-- "Considering the way that infidelity tends to increase the probability of divorce and considering the known ill effects of divorce on children, do couples have a duty not just to each other, but also to their children, to be faithful?" My answer to that question is: yes. Then there's the question whether people should be faithful even if they've redefined marriage so that infidelity is truly a non-issue (if such people exist). And there's also the question whether we have a duty to children not to redefine marriage that way. No, and no, to those two questions. But if the question is about people in ordinary marriages, I'll go for the idea that infidelity puts children in jeopardy, so the obligation to refrain is partly to one's children.

Consider this scenario: I have been dating a woman for four months. Though, for medical reasons, she is currently a considerable distance (over one thousand miles, at the moment) from me at the moment, we see one another very often when she is near. We get along very well and have grown very close; she is quite precious to me. We connect on an intellectual, emotional, and spiritual level (she and I are atheists). In sum, I'm quite lucky to have someone like her. She is a rarity. There is a good chance that I will be transferring to a college roughly seven hundred miles from our current location. If I receive the scholarship required to attend the college, I would be a fool not to accept the offer. However, I would be leaving this person I have come to know, like, and admire so much. Committing to a long-distance relationship with this person would be difficult for both of us. I believe that I'm more than capable of doing this: my sense of honor would prohibit me from engaging in behavior that would...

Since you are a poet, I hope you will not be offended if I focus a bit on the nuances of the way you tell your story. You speak of "this person I have come to know, like, and admire so much." You say "I'm quite lucky to have someone like her. She is a rarity." You say "she is quite precious to me." I don't think this is the "poetry" of love. (Is it?) Given what you say about your friend's serious medical condition, is it possible what you're feeling is deep friendship, concern, commitment, all very good things, but not exactly love? Maybe some clarity about your feelings would help you make the decision. I'm not saying it would be simple, even with that clarification, but at least it would be a start. My gut feeling is that a great scholarship is not to be turned down, and both love and friendship can continue at a distance. But there's nothing irrational about putting your friend first, if that's what you think is best. I'd just make sure I moved forward in a clear-eyed way. If...

I am a married man of 11 years with two children under 9 years. My wife and I are on the verge of a divorce and are waiting until after the holidays and figuring out the logistics of the house, finaces and child care. Nine months ago I met a younger married woman and since then we have been having an affair. We talk, text, email almost every single day. We see each other once or twice a month sometimes 2-4 days at a time. The emotional, mental and physical realtionship we have is amazing. We are like bestfriends and lean on each other for daily life issues. While my marriage is over her marriage is just starting the process of needing to change things drastically or it is over forever. She has been married for 4 years and has no children so while there is not as much to worry about it is still a very hard decision and she is taking things day by day. There is no doubt that we love each other but we obviously know there are many obstacles. 1) we are married 2) I have two children and she has none (and I...

If you really want to take a philosophical approach to your situation, then there are all sorts of things to think about--the ethics of divorce, the special responsibilities we have to children, the ethics of having affairs, the nature of romantic love, as opposed to the love we feel for our children. If you look at all those issues dispassionately, you may very well have to conclude that you have a duty to at least try to repair your marriage and preserve your children's home. I suspect, from the way you ask the question, that you want the advice that having a soul mate is more important than anything else and worth fighting for no matter what. I'm afraid I can't think of any good reason to believe that's true.
