Poetry for St. Valentine's Day; Love Poetry Challenge

A little while ago, Ariel posted a link to a great discussion of contemporary love poetry. It claimed that the stuff that passes for love poetry now-a-days is garbage compared to that which was written in, say The Renaissance.

Here's part of my comment:
I had a 17th. cent. poetry prof. who had a really compelling theory about why there's no good love poetry now. He said that all through the Renaissance, good old Petrarch & Dante & their cronies wrote out of the power & inspiration of frustration, from their unrequited love. Then along came the 17th century, when fat Ben J. & his "Sons" & the "Cavaliers" wrote their poetry of requited -- & consummated -- love. & that, this prof. thought, put an end to all the pent-up energy & poured out a whole lot of love poetry, & then ran out of ideas, ran out of inspiration. & here we are.

But I also agree with several other commenters who think that there's plenty of good love poetry being written right this minute! & my students are learning to do just that, among others.

SO I'd like us to take up the challenge! I charge you to post here, as a comment, an excellent love poem that has been written (by yourself or someone else) in the last 100 years. I'll start, by putting here my favorite by Edna St. Vincent Millay (perhaps the female Petrarch of the 20th century). I'd also love to hear some speculations on why love poetry has died, if it has.


Sonnet xxviii

I pray you if you love me, bear my joy
A little while, or let me weep your tears;
I, too, have seen the quavering Fate destroy
Your destiny's bright spinning--the dull shears
Meeting not neatly, chewing at the thread,--
Nor can you well be less aware how fine,
How staunch as wire, and how unwarranted
Endures the golden fortune that is mine.
I pray you for this day at least, my dear,
Fare by my side, that journey in the sun;
Else must I turn me from the blossoming year
And walk in grief the way that you have gone.
Let us go forth together to the spring;
Love must be this, if it be anything.

~ Edna St. Vincent Millay
