What you will do if you caught him cheating? Well many spouses would rather kill their husbands..hehehe, its only a joke.  Let's get serious because it is really a very serious situation especially for a married couple having a trouble in their relationship.  Solving a problem of your husband having an affair requires a serious patience and understanding on how it happened.  And you must willing to listen to his explaination so that you will reach a point to decide, whether to forgive or forget that you two are married.

Here is a cool explaination of a Married woman regarding that problem:

I just finished reading an excellent book that I believe will be an enormous help about marriage, but more importantly to the wives attitude about their husbands. The book is titled: The Proper Care and Feeding of Husbands and was written by Dr. Laura Schlessinger. I did not buy this book until I started hearing from some of my friends who had read this book about how it changed their attitudes towards their husband and how it changed ( for the better ) how they felt about their marriage. And so I picked up the book, and I started to read it. I saw myself within its pages, and how some of the things I said ( words) and a lack of desire for him, was destructive to not only our marriage, but to the wellbeing of our family and home. And the lack of desire was truly not personal ( meaning there was nothing "wrong" with him ) it was simply several years of marriage ( too familiar) and the demands of being a mother to 3 children ( their constant neediness ) caused me to simply desire my own space and i did not want anyone else "needing" anything more from me. But after reading this book, I understood ( finally) that my husband had every right to need me too, and to be loved and cared for, whether I was it the mood or not. Dr. Laura explained that there are many things we do in life that we are not really in the mood for. for example: do you simply stop working because you are not in the mood to go to work? Does she stop washing or cooking simply because she is not in the mood to do the laundry this month? Or does she let the baby cry and cry because she is tired or not in the mood to care for her child? And I finally understood each person has a need to be loved and cared for, and as a family, we try and meet these needs for one another. A few months ago, My in-laws and their best friends celebrated their 50th wedding anniversary. For their best friends, a party was held and they spoke about their love for one another, and how they still adored each other. My in-laws drove in seperate cars to the party, and avoided each other the entire evening. Although together for 50 years in marriage, they have lived seperately for at least 15 years...perhaps more. they are married, by they live seperate lives, and there is tremendous hostility and anger towards each other. I understand how marriages can reach this point. Marriage can be so hard. but it can also be something really, really beautiful if we make the small daily efforts and if is our desire to create a marriage that is beautiful. I do not know if she will accept this book from you and actually read it. i do not know if I would have read it if my husband had handed it to me. But because friends whom I respected told me about it, I read it too. And i have passed it on the a friend who I know holds alot of resentment towards her husband. Perhaps if you never mentioned it and she saw you hiding it in your sock drawer her curiousity would get the better of her, and she would read it. I don't know. what I do know is if she does read it she will be glad she did. There is alot of wisdom within its pages. I will discourage you from having an affair because if you look at the big picture, it makes it so so hard to put back together a marriage that is broken in this way. And if it causes a divorce, do you really want to see your wife re-married and your child calling another man dad? I understand this wanting to be loved and desired. I am hoping that you will both find this with each other. P. S. there are many weekend marriage seminars held around the country. I know for men that this is kind of a drag, but women can respond really well to these, and perhaps it will lead you down the path to the wonderful marriage you both desire. Let me know how things turn out down the road.

No easy answer to this one. I think a lot of people who THINK they'd leave end up staying and a lot of people who THINK they'd forgive find out they can't get past the pain. Each situation is so different - Was it a one-night stand? Was he drunk or hurting or just lost his job - or was she? Was he or she under unusual stress or - whatever. Also, if the person has been cheating for a long time, that makes a difference. If it is a one-time thing, that isn't great, but it depends on how forgiving the spouse is. No one is perfect.

Try to find out the root cause

When you finally could set your mind at rest, talk to him privately. Ask him why he is cheating. Is he bored with you? Has he lost interest to you? Could be that he is cheating because you don’t care about him? Regardless if you still want to be with him or not, knowing the root cause can help you prevent similar incident in the future. Understand this; there are 2 types of man; one that would always looking for some meaningless wild sex and the other that try to find a new romance. Some women might be able to accept the first, but rarely can accept the latter.

Give him a piece of your mind

After hearing all his side of the story from him, now it is your turn to talk. You have the right to yell at him. You are a tsunami of pain, sadness and anger. Take it all out on him. Cheating is by far worse than a polygamous.

Time to decide

When both sides of the stories are told, now it is time to decide. Regardless the root cause of the cheating, you must decide what works best for you. Can you accept & forgive the fact that he had cheated on you? Would you stay by him knowing that there is a chance that he might do that again? Don’t try to keep the broken relationship just because you had been with him for long time. This is personal and the right decision is not the same for all women. If you decide to end the relationship, end it gracefully.

Giving him another chance

If you decide to give him another chance, do not seek for revenge. Having an affair just to get even with him does not make sense. No one would benefit from that. When you have chosen to accept and forgive, payback is not justified. Everybody makes mistake. Since you have made the decision, you should not invoke this matter during future arguments. Evoking the incident is not going to make things better instead it might cause other issues in your relationship.

Seek Counseling

The next step is to seek for couples counseling. It is generally performed by a family therapist. Couples counseling is a confidential and non judgmental process that is aimed to help a couple to better understand and manage problems in the relationship.
