I tend to believe all love is true. No matter the circumstances, there is an element of two divine beings finding connection and experiencing something profound. It may be short lived, it may last a life time, or anything in between.
When people obsess over weather this one person is their 'one true love' or that person, it prevents the individual from getting to know the other individual.
This is a sort of self story telling. We imagine what our perfect mate is like, then look for if that 'one' person matches our expectations. Sometimes this mirage image we have dreamt up prevents us from seeing the real person before us.
That love, still, is real. Everything that has been or will be, is. Or so the story goes. Our story began at the beginning of it all, but neither you nor I were there when it happened, but we are still really part of the story of it all.
