We don't choose the one we love ,
it's a spark a feeling something like probability of our existence.

One mere atom falling out of line...... One out of a trillion ways to go wrong, yet  it went wrong in one specific way that resulted in our existence.

The moment you feel the spark will be the moment that LL be etched into your soul, .. that one moment in all of your existence will be the one where you feel the actuality and veracity of love.
