I owe you my life

I'm writing to thank you for teaching me everything i know,
I'm writing to tell you i don't wanna let you go,
You'll never understand the intensity,
Of how much you mean to me,
For every time you touch me i get tingles in my spine,
The one thing i long for is to say one day your mine,
For in your eyes I'm certain,
And in your eyes I'm sure,
That you will always be there,
When i come knocking at your door.
