Poetry Corner! Need a poem for ex-DP's wedding!!

[Crumplet]

I love my ex DP and he loves me but we are very happily separated and I am happily married with DCs. He is getting married soon and I am Best Woman (all a bit Bruce and Demi, I know, but we do genuinely get on and it was all a very long time ago etc etc)and I need to find a poem to tell him and his lovely lovely new wife how much we wish them well. Any ideas?

Tricky, because most of the best love poetry is too passionate for you to read under the circumstances.

How about this, by Nina Cassian? It is called

Postscript to the End of Love

Happy lovers - do exist,
they're always together,
their kiss invigorates, echoes...
Listen...listen...

Immortal couples do exist,
the ones who'll last forever-
their souls, even if parted shaped like
an idea or metaphor

They'll stay there forever
in that kiss, as if in light thunder.
Listen! Listen! Listen!
Happy lovers - it can happen!

Altho I shagged you
in the past
I hope your new love
truly lasts

Or is that going to lower the tone?

@grumpypants much better than my contribution
