powerful word

A four letter word
Combined with I and You
Just to tell someone
That powerful word
To someone else
And to them, it could only mean so much
Like a child and a mother.

why I love you, oh, so much,
when you're so out of touch.
Feelings that we could have shared,
you flung behind without a care.
It seems so hard to let you go,
and the process is so slow.
I don't know whether I should stay,
and waste another day away.
I do know, though, that all this pain,
will soon drive me insane.
You don't feel me loving you,
and you just can't seem to get a clue.
Yet still I find that you are blind,
to things meant to be kind.
You know nothing of my fears,
and are unaware of all my tears.
