Depends on how you define Soul Mate.
Does it mean "someone who understands me, loves me, clicks with me, and sticks by me for decades"? then yes. I have a few of those. They are friends I've had for over 30 years. Also, my half brother, who died about 17 years ago.
I don't personally believe in souls so the definition has to be explained to me in a different way... someone who gets the core of me? touches deep parts of me? loves them? Well, I'd say most of my partners *DID*. Just because it wasn't for ever doesn't me the love was fake. I really loved them. They really loved me. They totally understood and got me. It was just our dynamics that didn't work. Our behaviours and patterns and acting out. So who's to say ALL of them weren't?
My ex wife I loved more than all of them put together, though. But is intensity of feeling proof of ... what? Still didn't work because of dynamics. Nothing is perfect.
My friendships have taken a lot of work over 30+ years and a lot of patience and eyerolling and just letting things be and accepting shit or it won't work. And knowing when to work and when to just let it be.
I believe in chemistry, imprinting when young, social imprinting in your core group as you come of age, understanding things as a teen and early 20s seems to really "sit". I still carry the core beliefs of that - that's why I'm still friends with my friends.
And why I don't "click" with mainstream north american socially conservation traditional beliefs around romance and dating. I wasn't raised with it, so I don't "get" it. I was only introduced to it when I went gay and started dating American butches.
So when I meet those who "get" that same view point as me that *don't* come from my back ground, and they share my irreverent humour... I get excited we are working with the safe platform and understanding - that click.
Soul mate... being understood, respected, loved, "gotten", with shared vision/values. Yeah, luckily, I've had several.

and many are my friends
