'Till death do us apart', or well you know, divorce papers. 55% of all marriages end up in divorce, what does that tell you? More couples get divorced rather than getting their happily ever afters. Many factors can come into play which lead two people to end their marriage. The most obvious reason is that people make hasty decisions and they think it’s all good.
All is not good. All is far from good. Basing marriage on physical attraction alone is a huge mistake and people realise that mistake only after they're marriage leads to divorce. Although, I agree that if two people don't feel like they should be together then they shouldn't be made to be together but the fact is that two out of every three couples don't even have to go through with divorce if they follow these rules (cheating, lying etc. are all pretty obvious non-compromisable factors leading to divorce. This article focuses on other reasons):
1. Don't know each other that well.
Obviously two people do know each other to some extent which led them to the decision of getting married. However, they don't know each other well enough to get married just yet. See, the difference between dating and marriage is primarily the fact that you can't just end it without any consequences. Obviously, there will be some consequences when you break up with a partner but not as major as divorcing a partner.
Take your time; take as long as you have to. There is no age limit when it comes to marriage. You can get married really young or really old depending on when you feel like you're ready to take the relationship to the next level. Don't rush into marriage just because of that 'instant' connection.
