How do we reconcile what is universally forbidden, yet universally practised?

A couple days ago,social media was filled with people who were angry about the news that a husband cheated on his wife with a 19 years old girl. The shocking thing is they are only married for a few weeks,and has been in a relationship for eight years. Think you can still trust your partner now? Alright ,here's the thing,when I read about the news,I did not immediately picked sides,people were expecting me to pick side. Yes,so many of them were rooting for the wife. For me,unfortunately,I choose not to venture into the conflict,I am not obliged to do so. Why should I? You might say,oh its easy for you to say like that,what if you are in the wife's shoes. Excuse me,I am not obliged to be anyone's side. Right,back to the main point. You see,cheating are common these days. People no longer appreciate the sanctity of a relationship,or a marriage.There is always two sides to the story,remember this. The husband's and the wife's. You can't put all the blame on the husband,because I personally believed that both are equally to be blame for their own actions throughout the long years of relationship. 

Let me give you a situation,you are in a relationship. However,the longer the relationship is ,the more comfortable you are with your partner. You feel secured. And you tend to stop doing all those lovey dovey thingy because why should you? You already won the prize,and yes you think that the prize that you own now won't fall into someone else's hand. There are less and less communication between the both of you.Probably the other is busy,and the other one gets bored. And eventually ,loneliness kicks in as the other person no longer makes time. Yes ,people gets lonely sometimes. And when people gets lonely,they go out and talk to other people. Now,relationships are built on love, and sometimes two people forget to communicate causing unhappiness. And then when an opportunity comes along to talk to someone about their problems they usually do so, they feel like someone is filling that unhappiness but  at the same time start catching feelings and that’s where the problem lies. 

Does it always lead to cheating? No, not always, but most of the time, yes. 

There are two types of people. Those who pray on another’s needs to satisfy their own,usually are out for a satisfying relationship in bed and don’t really wish for a more significant relationship. And then there's those who didn't mean to cheat but circumstances evolved before anyone remembered to say no,these type of people who did it accidentally are guilty when it is over and feel terrible and are willing to face the consequences.

 Why do people keep the relationship while cheated on their partner? Because they need a fulfilment,and they don’t want to hurt the other person. That is a shitty thing to do,don't you think so? Because the other individual will be more hurt for the betrayal rather than the ending of the relationship. There are no clear answer as to why we betray someone by cheating rather than ending a bad relationship. This mystery remains unsolved,to a large degree.If you asked the cheaters for their answer,you won't get any,but hell they can give you a shitload of excuses. Excuses which doesn't matter at all as much as the pain that's caused.

What do infidelity means? Why do we think that men cheat out of boredom? And women cheat out of loneliness and hunger for intimacy? Why do happy people cheat? An affair,is the simple act of transgression that rubs off a couple's identity,happiness and relationship.And yet, this extremely common act is so poorly understood. 

How do we reconcile what is universally forbidden, yet universally practiced? 

The double standard is as old as adultery itself.

We used to believed that we are reserved to one person per life. Today,it's one person at a time. We are a walking contradictions, most of the people who say that it is wrong to lie about having an affair but they also would lie about having it. We are a paradox. We have this whole idea of being a romantic couple,and because of this romantic ideal we are relying on our partner's fidelity . But,we tend to stray, not because we have new desires, because we live in an era that we feel that we are entitled to pursue our desires. 

Long time ago, people ended their relationship because they are unhappy, now people cuts off their relationship because they can be happier.

Cheating is a betrayal,everyone gets that . But let me direct you to look at other perspective. What if cheating is  an expression of longing and lost? Instead of blaming the person for cheating,have you ever look at what is wrong with yourself? Have you ever noticed the reason why your partner cheated on you might probably because you did not communicate with him/her? Have you ever take a second to look at all the things you did wrong that might have pushed your partner away to find happiness elsewhere? Don't blame their desire to be happy because everyone deserves to be happy. 

At the heart of an affair, you will often find a wish to recapture lost parts of yourself, a wish or an attempt to bring back vitality in the face of lost and tragedy. It is not much that we are looking for another person, but as looking for another self. Most people do not engage in affairs because of sex, but more about desire, desire for attention, desire to feel special, desire to feel important. 

Now look at your relationship,have you done enough to keep your sweetheart?
