When an affair occurs it marks the end of the relationship as we know it. This being said, a new, possibly stronger, relationship can develop in its place. The couple can never go back to the relationship they once knew. If they choose to move forward they can create a new relationship together. It is difficult to move past betrayal and is only done with great effort. The betrayal cannot be swept under the rug and you can only move past it once it is in the open and has been properly dealt with. The person who feels betrayed must feel as though their feelings are completely understood before they are ready to move on and build anew.
