We're told to believe that in order to be happy, we need a partner. No one can grasp the idea that some people prefer to stay single. There are many people who're in relationships and we're quick to categorise them as some of the happiest people in the world, in contrast, we categorise single people as sad individuals who haven't found love yet. The truth is, even if they do find someone worthy of being their 'soulmate', these individuals would rather stay the way they already are than to begin a relationship. Why?
1. Being in a relationship doesn't make anyone happier than not being in one and vice versa.
Everyone has their own outlook on life. Some people believe that finding true love is the purpose of our lives, whereas some people believe that it is not. Rather, they believe that happiness shouldn't be limited to another person being in their lives. To call single people 'lonely' would be unfair because being single i.e. not in a relationship, doesn't mean that they don't have friends. It doesn't mean that they're socially awkward, it means that they just don't see the point when others say that love is necessary.
Maybe their love isn't in one person, it might be with their family, friends or even pets. Whatever it might be, being single doesn't make you any sadder than someone in a relationship and being in a relationship doesn't mean that they're any happier than someone who's single.
2. They don't want to go through all the work.
It's a matter of choice whether someone accepts the work there is to a relationship or whether they choose not to. It doesn't necessarily have to make a person shallow. It's their choice. Some people will disregard the happiness that is possible in a relationship and focus on the cons instead.
When a relationship ends in either a break up or a divorce, there is undoubtedly grief and anger and these people have seen enough of that to conclude that being in a relationship will ultimately lead to regret.
