How many marriages have survived infidelity?
I come to realize that it is more than you think. It is easy here on Y/A to say: divorce him but many of the marriages that are celebrating their 20th or more anniversary may have had their share of infidelity along the way. My view is not for men alone, women are also included. I think that it is very hard and so difficult to start again as it takes so much energy to build a relationship. I think that forgiveness and a good confession is easier to handle than starting over with a new devil that you do not know. I would advise you to stay, have a serious talk, bring closure to the story, mourn the days that you feel hurt ( you are only human) and move on. Once you have taken that decision, do not make a mantra out of that situation. I hope that I have been of help.
There are many marriages that survive infidelity. It is up to the couple. Sometimes the person who cheated is truly sorry. Sometimes they are not. It is up to the other spouse to say yea or no they are willing to work it out since it is grounds for divorce. There are so many factors that come into play. Forgiveness can be golden. Many never cheat again and things work out with communication and trust being rebuilt.
