Wah lau 18 years no quarrel is not marriagelah. Which married
couple no quarrel one. Sure have. If don't have then the marriage
not healthylah. Of course that depends on what kind of quarrel.
Money, children and inlaws are the main topic for quarrel.
Ex:-
I want to buy her 2 carat diamond ring (since I made a bundle from
the STI), she said save it for the family trip instead, so quarrel
loh. I disciplined the two monkeys. She heart ached disagree on my
style of discipline, so quarrel loh, but not in front of the kids
lah. She wants to go visiting my mother every weekend but I one
lazy bastard, prefer to stay at home to sleep the weekend away or
play mahjong (luckily she like that game too). So she don't like my
attitude said I'm unfilial and show bad example to the kids so
quarrel loh.
Then I like to eat 'ter kah' pig trotters, she don't let me eat,
reason: too fat 
quarrel lagi. So, mei wan mei liao but in
the end we must all learn how to compromise. Give and
takelah.
So, don't worry Shinta, always talk things out, hokkien says 'bo
ngam kong kau ngam' as long it don't get out of hand. Your marriage
still in honeymoon period, so enjoylah
