with that i say i'm sorry

this one is a little hard to explain

I never thought I'd fall in love.
I never thought I'd love this much.
I live for you,
I breathe for you.
I hate myself for you.
Do I love you too much?
Do I try too hard to make you love me?
I'm sorry,
but I think I love you too much.
So with that I say I'm sorry;
I'm sorry for the tears on your pillow
and
the tissues on the floor;
but most of all...
I'm sorry for the blood stains on your carpet...
