"but is love and romance without the need and longing for a loved one? " -

My opinion
Love is one of the thousands of words of meaning.
When we say love him/her, whether we are sure the phrase love is really true love or just sheer obsession?

In fact, many people who hurt his partner, but he insisted that his partner loves. There are also people who are willing to wait and pursue the gebetannya years in the name of love. There are also couples who meet in person some day a new love. Whether any of it true love? Or just making this up for the sake of satisfying the sheer obsession?

Though love and obsession is sometimes very difficult to identify, you should be able to tell the difference. For the sake of not only yourself, but also for the good of others.
