Love Poems Wanted

I'm going to be sharing a stage with Fiona Shaw at the Verbal Arts Centre on Monday 23rd April at 7.30 to talk about love poetry. Marie-Louise Muir will be interviewing Fiona and it promises to be a great evening. Here is a link to the event

I'd really appreciate it if you would let me know which is your favourite love poem. I have a few in mind but would really like some more ideas!
Thanks
