John Donne

Womans Constancy

Now thou has loved me one whole day, 
To morrow when thou leav’st, what wilt thou say? 
Wilt thou then Antedate some new-made vow? 
            Or say that now 
We are not just those persons which we were? 
Or, that oathes made in reverentiall feare 
Of Love, and his wrath, any may forsweare? 
Or, as true deaths, true maryages untie, 
So lovers’ contracts, images of those, 
Binde but till sleep, death’s image, them unloose? 
            Or, your owne end to Justifie, 
For having purpos’d change and falsehood, you 
Can have no way but falsehood to be true? 
Vaine lunatique, against these ‘scapes I could 
            Dispute and conquer, if I would, 
            Which I abstaine to doe, 
For by tomorrow, I may thinke so too.
