If you found out that your husband had fallen for another woman ?

When a hurt is new and fresh and acutely painful, it feels like it will never go away. But the saying "time heals all wounds" is around for a reason. Give this time. Be honest with your husband, and talk about this and ask as many questions as you need to. Whether or not he understands the gravity of how he hurt you will come clear over time, and if you get to the point where he shows genuine remorse, your feelings may start to change.
