Can anyone fall in love ONLY ONCE in thier life?

I believe you can love many people, but falling in love is different. To fall in love is a special thing that happens very few times, for some people only once.

So, once I'm in love there is no turning back. Hopefully this is once in my lifetime. 

“When I saw you, I was afraid to meet you... When I met you, I was afraid to kiss you... When I kissed you, I was afraid to love you... Now that I love you, I'm afraid to lose you.”
