Romance- a dose too much?

Why is it so difficult to express feelings properly? You know you like him, he knows he likes you....why isn't the rest as simple as that? These complications, they make life so much more convoluted than usual. Is it absolutely necessary?

The quest for true love is never ending and at this point looks seemingly impossible. We are waiting for our knight in shinning armor to arrive and sweep us off our feet with these unrealistic expectations. Love isn't as beautiful as it is portrayed in movies. Sometimes there is pain, expectation, jealousy, guilt, and heartache. Love - that pleasant heartache when you see him walk by or when you talk to him. Or when your heart skips a beat when you think about him. You want to spend your future with him. Every time he breaks your heart, you want to hate him but the next moment he talks to you, your heart melts and all the anger goes away. WHAT IS THE CURE TO THIS LOVE DISEASE? It may just be the hormones of adolescence but it is not.

When do you know when you are truly in love or if it is just infatuation? Will we ever know the answer to this question?
