You made me feel silly with your question.
Thinking about it, that doesn't make many sense...why every people have to follow the same paths, why getting into adulthood means to setel down and build a family? It's surely a biological, cultural and irrational thing... but I can deny that for almost every people to be 'happy' is having someone by their side. In my way I'm a lonly person. But I like love and care, I like to be loved and cared. But there are always two sides, what you recieve and what you can give. And what can I give in many different ways? Nothing. Nobody is perfect but I'm completly sure the 'good' things I have aren't enough and never will be. It toke me sometime to understand that, but I did. I'm pretty sure nobody that I like will like me if they know me well...the funny part is that nobody can come close enough to at least know a little bit about me. So the best I can do and I can be, is stop being selfish about love and recognize it. But I'm tired of sociaty's pressure, everybody in their long term relationships just waiting for graduation to be a new family... I'm tired of my family's pressure. And I can't be imune to love, where it is a good or a bad thing. I can't predict my future, if someday I will have real friends to fill my live. So this is my choice, I'm just not sure if this is another solution to unhappiness.
