I think love is a wonderful thing. It is, however, a fickle emotion and one that can change as quickly as the wind.
Marrying for love has its ups and downs. As soon as someone feels they are not "in love" anymore, they quickly go about making plans for an exit, hence contributing to the 60% divorce rate in America.
In my mind, arranged marriages have their ups and downs, too. Though one may have a successful marriage, this does not mean, however, that one will ever know love.
From what I've read, arranged marriages tend to be more stable and last longer than marrying for "love". It therefore, comes down to whether one wants to gamble on love or seek the stability of an arranged marriage.
