I have an unusual situation with my Twin Flame and Soul Mate, as well. My Soul Mate is definitely the man I've been married to for the last 9 years... he and I are so much alike that it's kinda frightening, but at the same time, we're exact opposites which brings a nice balance.
My Twin Flame is a different story. We found each other almost 6 years ago and the similarities are uncanny. We do everything the same. We get sick together, our kids go through the same things at the same time, our pets even got the same illness at the same time with identical symptoms. We thought it was a bizaar series of coincidences until one day when I asked her to take a drink of water. She asked why and I replied, "Because the pill you just took is leaving a horrid aftertaste in my mouth." What made this so unusual is that her and I have never been face to face. In fact, I live in Canada and she lives in South Carolina. I've been in operating rooms during her countless surgeries and she has been with me during my difficult times. We have shared all five senses at some point or another. We can text each other out of the blue with half-thoughts and yet we both know what we're talking about.
We were building websites together and kept them secret from each other just to see what would happen and we both designed sites based on medieval Scottish castles... using several of the same images. We have deja vu of conversations we know we've never had in this lifetime.
She is my twin sister as far as we're both concerned.
I just wanted to share this because I believe that Twin Flames don't always have to be members of the opposite sex or have romantic relationships.
