It Makes Sense If You Want Your Marriage to Work
I want my marriage to work. I want it to be happy. I want it to have longevity and I want it be a solid foundation for the rest of my life.
I cannot see how that could work if one or both of us decided that we would see other people. I believe that it would create seeds of doubt, that would erode the trust that is essential for a marriage. If she started cheating on me, I would always wonder, will she find someone who is better than I am. (Better can be anything from better in bed, to richer, to more handsome, or gives her something I can't.) Would she leave me? What if I found someone who was better? Would I be content to stay with my wife who was not as good as my lover?
I know some say that the cheating helps them, maybe it does a few, but there are a lot of people who say that cheating has ruined their life. It may started out as a mutual decision, as something they thought would be good, but it bit them. (I some how believe that half of the stories you read on the net about open marriages are fantasy or embellished.)
Hey, what I have may not be great, but I would never do something to sacrifice it. I will stay true to my wife.
What you do is your business, but maybe you should think about it a lot before you do it. Once you do it, it cannot be undone!
