Depending on the situation, you may want to do one of the following: 1. Confront your spouse about the cheating: If confrontation results in a fight and both of you end up angry, then moving on may be the best option for both of you. The fact is, you both deserve to be happy and if this means that you have to go your separate ways, then so be it. 2. Try rebuilding your relationship from scratch: This is a tough decision, but often times the best way to heal the wounds of a cheating relationship is to start from scratch. This may mean setting boundaries, communicating more honestly, and committing yourself to rebuilding trust. It can be a long and arduous process, but it may be worth it in the end. 3. Just move on: If confrontation doesn't happen or goes poorly, then sometimes just moving on is the best thing to do. You may grieve and feel heartbroken over the cheating, but ultimately it's up to you whether or not you want to continue trying to rebuild your relationship.
