muffinmonster, I used to feel like that. I guess I didn't really believe all that 'love of your live', 'the one', 'soulmate' nonsense. it didn't matter though, because I didn't need anyone except DCs...
Then, one random day, I met DH and we loved each other. instantly. And I realised that all those cliches, and others like 'two pieces of a jigsaw' were actually possible.
I do remember life before DH though, and I absolutely accept that if a person hasn't literally fallen in love with their solumate at first sight, they will think it's all twaddle :)
I read some research once, which reckoned that about one in ten of us meet our soulmate. TBH I can't remember how the study was conducted (and it would have to be a bit subjective, wouldn't it?!), but if I think about all the people I know, I reckon that's probably about right. DH and I constantly feel very lucky.
