I think rosesformoi's thread's been really interesting. It's good to see such questions answered from all perspectives. The only thing that puzzles me about those who "cheat", is that they ALL seem able to justify their actions, without seeming to give a thought to the feelings of their spouses. Women often have an inbuilt intuition that their partner's straying, so for someone to say that they're getting away with it - or using discretion - might not always be the case. Many women'd prefer to close their eyes and keep the family together - or to be the one who keeps the ring on her finger - but surely the innocent party must be very hurt - or WOULD be, if they ever found out? Also, from the point of view of those who DO cheat, could they ever trust the object of their desire if they were to get together? I also think there's a world of difference between having a friend of the opposite sex that you can have a laugh with, and spending hours on online flirting, because that IS cheating in a way. You're cheating the partner at home out of giving THEM the time instead. This is just a personal observation. All situations are different anyway, and this thread illustrates it. It's been a good read.
