Alas! 'tis true I have gone here and there,
And made myself a motley to the view,
Gored mine own thoughts, sold cheap what is most dear,
Made old offences of affections new;
Most true it is that I have look'd on truth
Askance and strangely; but, by all above,
These blenches gave my heart another youth,
And worse essays prov'd thee my best of love.
Now all is done, save what shall have no end:
Mine appetite I never more will grind
On newer proof, to try an older friend,
A god in love, to whom I am confin'd.
Then give me welcome, next my heaven the best,
Even to thy pure and most most loving breast.
Of course its beauty is enhanced for me by the fact that I connect it with a lovely lady from my past.
This one is a perfect description of what the psychologists call post-coital tristesse:
The expense of spirit in a waste of shame
Is lust in action; and till action, lust
Is perjur'd, murderous, bloody, full of blame,
Savage, extreme, rude, cruel, not to trust;
Enjoy'd no sooner but despised straight;
Past reason hunted; and no sooner had,
Past reason hated, as a swallow'd bait,
On purpose laid to make the taker mad:
Mad in pursuit, and in possession so;
Had, having, and in quest to have, extreme;
A bliss in proof,—and prov'd, a very woe;
Before, a joy propos'd; behind, a dream.
All this the world well knows; yet none knows
To shun the heaven that leads men to this
Sorry to wander off-topic, but it's my party and - oh you know the rest.
