We may have been in love that time

[lucentwavering]

We splashed down the street;
though our minds held hands,
our fingers dared not touch. - Is the word 'down' a bit too heavy in stress? Try 'in'. Then take out 'though'. 'dared not' seems somewhat contrived. Maybe 'not daring to touch.'

Conversation spiralled, spilling,
breaching walls as yet unseen;
floodwater filled our ditches. - the commas seem to me somewhat unnecessary and restrict the building rhythm of the verbs. For some reason I want to see the third line inverted (our ditches filled and flooded, for instance)

Puddled reflections mirrored two
creatures of different breeds
too alike to wade in deep. the first line of this stanza is my favourite. The last line needs to be filled out a bit, rhythmically.

We may have been in love
then, but showing it
would shatter tainted calm. - that last phrase is lovely.

I kept my head above
but lost you, once the waves
we made caught up. - I find the comma unnecessary. Otherwise, I find this quite delightful. The rhythm is somehow beautifully defeated and sour.

Nicely done! This is a strong piece of work.
