Bigamy is one wife too many. Monogamy's the same.
(Oscar Wilde)

Abstinence makes the heart go yonder.

Women inspire us to great things, and prevent us from achieving them.
(Alexandre Dumas)

Sigh no more, ladies, sigh no more,
Men were deceivers ever,--
One foot in sea and one on shore,
To one thing constant never.
(William Shakespeare, "Much Ado About Nothing")

American women expect to find in their husbands a perfection that English women only hope to find in their butlers.
(W. Somerset Maugham)

As to marriage or celibacy, let a man take which course he will ~ he will be sure to repent it.
(Socrates)

V
'T is melancholy, and a fearful sign
Of human frailty, folly, also crime,
That love and marriage rarely can combine,
Although they both are born in the same clime;
Marriage from love, like vinegar from wine -
A sad, sour, sober beverage - by time
Is sharpen'd from its high celestial flavour
Down to a very homely household savour.
VI
There's something of antipathy, as 't were,
Between their present and their future state;
A kind of flattery that's hardly fair
Is used until the truth arrives too late -
Yet what can people do, except despair?
The same things change their names at such a rate;
For instance - passion in a lover's glorious,
But in a husband is pronounced uxorious.
(Lord Byron, "Don Juan," Canto III)
