Is Love A Choice, Really?

The butterflies you feel in your stomach, the anxious, nervous, excited emotions that Come over you when you hear and/or see a certain someone. 

Are these all intentional or spontaneous?

 The longing, yearning, the desire... Heartache, pain, grief... Voluntary? Involuntary? How is it that you can feel one way for someone and another way for someone else? People say they just found love, stumbled upon it even, 

As if it appeared out of thin air and has been the greatest thing to happen to them. Others feel that is was developed over time. 

Something that was plotted, in a sense, and then executed. 

I guess in the end it comes down to how much you want to romanticize the thought of Love. 

It is an emotion, whether autonomous or natural, seems to be very debatable. 

However, the most stifling question for me seems to be... 

IF voluntary, When does it no longer become a choice? 

At what point can you not help but love someone no matter what? Or is this also Something mental and controllable as well? 

Im at a loss, confused, if you will...
