Marriage is sweet; many single persons wish to be in it at just a glance at other’s pre-wedding photos, but those already in it, well let’s just hope for the best. But you can always call me if it doesn’t work out.
At the end of the day, it’s a divorce, constant fighting or just extra marital affairs that’s becomes the other of the day…, c’mon couples, we are bigger than that.
These are some of the reasons why you may want to cheat on your partner and the earlier you know this, the better because you can just avoid it!

Early marriage
People who marry in their early 20s would most likely have achieved some level of stability and social standing by their mid-30s. At that point, they feel that they did not really enjoy life in their 20s, and find it exciting to indulge in an extramarital affair. It is their way of experiencing the thrill and excitement of dating.

Married for the wrong reasons
Many people enter into marriage for the wrong reasons. If they meet someone who is in any way a better match than their current spouse, they are immediately attracted to him/her. And what starts as a simple friendship usually ends up in an affair.

Life throws changes at us almost every day. Most of us are able to deal with the small changes. But the bigger ones are tougher to deal with — a serious illness in the family, death, loss of employment, financial loss, etc. Many turn to people, apart from their spouses to deal with such changes.
