Being married is not a problem but would be a problem when as a single, you don't prepare the foundation for marriage properly. Just as for every super~structure there's a mighty foundation, the same applies to marriage. So here are 4 concrete reasons why marriages fail!

people don't love themselves; self-love is necessary to make a good marriage, note; that am not speaking of selfishness, I am speaking about being happy with one's personality, before you get married as a single you have to develop a level of self-worth for oneself, and also self-appraisal. So many run into marriage because they think they would find happiness from another person, not at all dear; marriage isn't a rescue mission, imagine if the marriage didn't exist again would you still happiness within you, loving oneself also installs having a sense of fulfillment or completeness with oneself.

people don't love each other;  most times divorcees are always having this kinda statement saying things like " I detest him or her" then you ponder over how they got married in the first place. The very reason this happens is due to the fact that they never actually loved each other in the first place, factors that spring up this are when people set marital goals..... e.g fixing a particular age to get married, and when you get up to such age and the forthcoming signs of marriage, you naturally get tensed up and desperate to see it happen. Another factor is that of being enticed with fantasies about marriage.... mostly amongst ladies, so what happens is that they love the idea of getting married more than loving their partner.

 people don't build and develop themselves before marriage; your years of being single are times when you undergo packaging, development of skills, development of character, building financial capacity, endurance, forgiveness, and some other life's important virtues, so when this isn't done by any of the parties, they come into marriage having nothing to offer or lacking virtues to sustain a marriage, most times people are advised to look out for individuals accomplishment and not potential before getting married, so when any party lack some crucial and necessary capacity for marriage, there are possibilities he/she won't make a successful marriage

 people fail to understand the difference between men and women; take it or leave it, men and women are totally two different creatures and the earlier couples understand this the more successful their union would be, looks like men are from Mars and women from Venus talks a lot about this. Some  important distinguishing factors are below; 

  For Women;
* Attention~  note; that every woman needs attention, mark my Choice of words, I said need and not want.
* Humour ~ a very important ingredient to still keep and maintain intimacy and bonding
* Romance~ as a matter of fact, every woman is an emotional being, so little acts of romance, like surprises, will always create a successful marital life.

For Men 
* Acceptance~ every man can't endure the feeling of being made to feel less than a king, in his home, corrections done with an idea of advising him will always work
* Help; men are fond of not being well organized, so they need help from women who are multitaskers 
* Respect; take all from a man but don't tamper with respect him in his home, in other to have a successful marriage.

When these proven facts are neglected a successful marriage would be found wanting!
