No. You don't. You don't have to be in a relationship because other people are in it. You don't have to be in a relationship to be happy either. Happiness is within you. And if it isn't already you should try to find it inside you. Not in a woman. Simply the only reason you should be in a relationship is because you have that significant other who you want to be with and care about deeply. You shouldn't go around searching for a girlfriend. When it's time you will know it. Until then focus on yourself.
