My idea of a soulmate in one word in two words is organic and synergy.
Love takes on different forms but it is generally two souls who find each other, are bonded to one another. Someone that you can overcome every obstacle with, someone you see the same way now and the first day that you connected, immense respect, love, empathy and understanding. Someone that gives you the platform to be your true self, to lift you to higher plains.
If is not an easy question but those are my brief thoughts.
Sounds to me like you get it. So if should happen to meet that special someone then you will know for that she is the one. That is if you haven’t already. Thank you Waz for your heart felt comment.
