I don't know why people are hung up on the 'one' aspect of it and then tell us that statistically of course you can't be designed to meet only one person...yep, that's right.
That doesn't mean, though, in my opinion, that you can't have a soulmate. It might even be more than one soulmate in a lifetime, but I don't think most people are that lucky. I would describe my husband (he's passed away now) as my soulmate, because no-one else came close to the level of physical, emotional and mental intimacy that we had, we simply were entwined in a very deep way and it's been very very hard to even consider going on without him.There seemed to me, at least, that there was a soul or spiritual connection, and that's why he's my soulmate
I don't know if it's possible to have another one, having dated a bit and seen others, I suspect not. Time will tell.
I also think souls can meet non-romantically, and that just saying you 'love' someone doesn't always do justice to that.
I don't have a Disney approach to life, but neither have I got a pragmatic one, I was happy to stay single or not settle down, even in mid-thirties, until I met my soulmate . There weren't 1000's of people I was compatible with, in fact, I had difficulty finding one and even in that one, soulmates are hard to live with!
