How do you know THE ONE is "the one"???????????

How did l know the "one" was THE ONE??

I first laid eyes on him  when l was about 11 years old. I dont remember much about the day other than it was at a gathering of sorts and l just remember seeing him. Although he was not that  near me, or did not talk to me, i remember being aware that l was blushing literally up to the roots of my hair.  I remember thinking what the hell is wrong with me, why did l just go bright red. Then we left the area but l do remember the next time l saw him l felt exactly the same and suddenly it began to dawn on me. I would literally have butterflies when l saw him.
The fact that he was a team mate of my brother's did mean l saw him pretty often. all the way through my teens in fact. we became friends. 
I never thought l was in his league so it meant l had great fun with him, in his company.

Many many years later the fact that he found me attractive blew my mind.......
the fact that we got together, travelled the world, bought a home, got married and had our beautiful children together is still mind blowing..................
he would cringe if he read this, but l love him to bits and feel lucky, so lucky...but hey, he didnt do too bad either xxx
