If the husband only cheated once and the couple learn good communication skills then it’s possible they can have a happy marriage, but, it will take sometime for the wife to trust her husband again and he is going to have to earn it. Humans make mistakes; emotions can run high and if he has learned from this mistake then it shouldn’t happen again. The wife should make it clear if she even gets a hint of him cheating again that will be truly the end of their marriage. Take an hour out each day and discuss anything and if either of you have problems then be open, calm and fair about it and listen to each other. No one said marriage was easy.
