From the beginning I thought my friend's marriage was perfect and they were right for each other. They have two sons, go everywhere together. The other day she was at my house. We were sitting around talking and drinking wine. She tells me that she cheated on her husband once. Now she feels guilty and swears she won't do it again, she started crying. She says she was in a state of confusion at that moment. I advised her to confess to her husband, he will forgive her and you will live well. I sympathize with her, but it seems such a heavy deception and so can not live in the family. I don't know how to support her.
