Heartache remedy? Resolution attempt #2

Previously, I used to think that the term 'heartache' was a misnomer, since people of earlier times used to think that the heart was the seat of emotion rather than the brain. Now I realise that it actually does hurt your heart physically/physiologically.

In infancy, you learnt to avoid pain

Basic survival instinct/mechanism 

You pull your hand away from the hot pan

And cry in protest at the nurse's needle

These, you do even now, yet

Hold on to love while it rips you apart?

Where are your defences when you need them?

Where's 'reason' that you hold so highly?

Oh, the rationalist when arguing on everything else!

Aren't you the hypocrite that can't 

        reason your way out of this!

Since you couldn't muster the courage to tell her

Despite all the "this time I'll do it!" resolution

Please try to forget for a while

Lock it up in the basement of your mind 

Until you turn less cowardly in will

Please! Please! I beg of you!

Do not let this be what you point your finger at

When time has moved past and you come to realise

You've missed the chances that took much to create

It is not fair to her, this ever comes to pass

For what's her to do for your lack of resolve?

Her kindness alone is her fault, that I know.

Please! Just let it go for now...
