In my opinion, nobody can be sure that he or she will fall in love with a person and even if he or she falls in love with somebody, that person will fall in love in return. If you don’t fall in love or not get a right person, then you can think of arranged marriages. Even in arranged marriages you can know the person well before you decide to get married. You should make sure that your proposed partner likes you as well and is not agreeing for the wedding because of any pressure from her / his parents or any other reasons.
