'But I'll do my heart out'
I think this line would be better if it were 'I will pour my heart out'
'Until I search your soul'
This one would be better if it was 'Until i reach your soul
'
'So what we have won't go to waste'
You must add 'that' between so and what
Just my suggestions.
I loved how you introduced the poem with that line proclaiming it was that time to have your love or it would never happen. The way you express your emotions is wonderful and the words used are appropriate. The last lines show just how much you are willing to go or do so that this love will not die but must endure and last forever. Short but heartfelt and well written. 5
