When Does It End?

I love you so much,
But you will never know,
Because I can't ruin,
The relationship we have grown,

Your are my best friend,
Which makes it even worse,
That I can never have you,
And it really, really hurts,

I care for you so much,
Yet you don't realise,
That when you talk about your boyfriend,
I get tears in my eyes,

I want to stop loving you,
I really do,
But I just can't,
Because it's you,

I will never want someone as much,
I will never cry so many tears,
For the one person,
Everyday of the year,

Even if I stop loving you,
It will start again and again,
And then I will ask myself,
'When does it end?'
