Love before and after marriage takes a different form. Whether a
relationship lasts after marriage depends on how it has evolved, or
devolved.
There is one example with marriage after 7 years of courtship,
marriage now moving towards 6th year, with a sweet little
boy.
There is another example. 0 years of courtship because of
match-making. Happily married for about 33 years without any
quarrels at all.
There are of course numerous other examples where short and long
courtships fail to evolve into marriage, or resulted marriage last
or break. The fact remains that you would never know until you die
with your spouse by your side.
It is all about how love evolves in managing a relationship as it
changes first from courtship, to marriage, to co-parents.
