Fate and Fireworks

Do you believe in fate?
One person 'made' for each one of us?
Or do you believe that fate is a myth and that there are possibly quite a few people that we could get along swimmingly with for the rest of our lives.

I used to believe in fate.
Now I don't.

New topic:
Have you ever had fireworks with someone? Not just your average 'butterflies' feeling but such an intense attraction that you couldn't hold your hands steady if you tried (never mind the rest of you), that forming complete sentences was monumental because as soon as you were around him every intelligent thought left your brain. That you would avoid looking at him in a crowded room because if someone saw the two of you making eye contact there would be no way of disguising the chemistry you two had. He's the guy that you felt you had no natural defences around. The one you felt intensely drawn to with no logical explanation. The one that when you made eye contact, the air seemed to crackle with the electricity and everything else in the background went all fuzzy.
I have.
But only once.
And trust me, it's still pretty unforgettable.
What I regret is that I didn't pursue it at the time because it was so intense, and I was afraid that it was only one sided and I'd be rejected. I didn't take the risk. And now I'm left to wonder.

My question is does it ever happen more than once?
Or is it so rare that not everyone gets to even have it the one time, let alone more than that?
