How is less important than whom you get together with!
Ultimately if a couple is happy being together that's all that matters.
Generally speaking in the U.S. we have not had arranged marriages.
However I suspect in other countries and cultures where this is a normal practice they're likely to be very religious as well and unlikely to divorce whether they're happy with their marriage or not.
Our society tends to judge the "success" of a marriage by how long it lasts rather than if the couple is (happy together or remain in love).
There are lots of couples who are "emotionally divorced" in sexless marriages. In some instances living in different areas of the house.
Some people also don't believe in divorce no matter what. Cheating, verbal/physical abuse, neglect, alcohol/drug addiction, living in different parts of the house and barely speaking...etc
They'd rather cope with unhappiness for life than go through divorce.
