I just joined this site, but this thread caught my attention because I did meet the person I consider to be my soulmate (although I think of him more as being my twin flame since to me a soulmate is someone who is part of my soul group). He died on Sunday, which led me to this site. I will say that meeting him was different than any other relationship I've experienced. We were enthralled in one another even when we were apart. We love each other unconditionally though and that love has survived through his death. I mourn for him like I'm his widow, not like he was just a friend or an old love. It wasn't even about the physical contact, it was about the boundless unending love that was between us from the moment we met.
With that said, I think that love is different from an earthly marriage because when you become with someone on a soul level, that bond can't be severed. Not by anger, not by death, not by anything. It actually reminds me of a verse in the Bible, although I'm agnostic. "For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord." - Romans 8: 38, 39 And I think that's what finding that person is really about. It's about experiencing and expressing the unyielding, unconditional, and eternal aspect of what love truly is.
