Unrequited (It's love; but without it!)

Love unrequited - the flame of love ignited

Un-reciprocated - it's love but it's understated

I'm not undecided - maybe I'm misguided!

Unconventional?  - yes! am I in a mess?

Sure! - don't you doubt it!

It's love; I want to shout it!

...just not consummated - it's love; but without it!
