Forever and Always

How can I have a feeling that is this strong?
Only by thinking of you, I feel tears are welling up my eyes.
Why?

Should I be out of line if I say I love you?
I love you more than anyone else, anything else.
Even more than my boyfriend, my family.
You're my everything.

You're the only thing I can't let go.
But if I have to, but if it makes you happy,
I'll learn how to let you go.

And if I let you go, and if you're gone,
There's only a few things that I'm sure of:
That I'll cry for days because of your leave,
I'll never get over you,
I'll never forget you,
I'll always love you.
