Where there's marriage without love, there will be love without marriage.
It is not a lack of love, but a lack of friendship that makes unhappy marriages.
There is no observation more frequently made by such as employ themselves in surveying the conduct of mankind, than that marriage, though the dictate of nature, and the institution of Providence, is yet very often the cause of misery, and that those who enter into that state can seldom forbear to express their repentance, and their envy of those whom either chance or caution hath withheld from it.
Keep your eyes wide open before marriage, half shut afterwards.
More belongs to marriage than four legs in a bed.
