If either me or my wife developed feelings for someone else we'd just be honest about it. There's no point not being, to be honest.

Also, I (both of us) think that this "emotional cheating" thing is utter bollocks, you should be able to have as many people in your life as you want who you can turn to emotionally and be emotionally close to, and whether they're male or female shouldn't matter. You only get one life... Closing yourself off to close relationships seems like a needless waste. If your partner having emotional closeness with someone else makes you feel insecure then you have problems already. In my opinion.
