Some would say that love and happiness go together. If you have love, you must be happy, and if you are happy, you must have love. I hate to shatter this beautiful illusion, but in many cases this isn't true. Most people who go through depression are loved. But no matter how much love they have in their life, they just aren't happy.
Many people marry for love, and end up miserable.
They try to stick it out because they love each other, but they are never really happy. Now, I believe love is the most beautiful emotion in the world, and if you go through life without loving someone or being loved by someone, then you haven't really lived. I don't think so. There are many examples of people who have made choices for love instead of happiness. For instance, some people choose to give up the career of their dreams in order to stay with the person they love.
