Yes they are allot less fragile…because you marry out of certain expectations and obligation, so it is allot more difficult to get divorce since it’s a marriage that is set up through family. Plus when you get into an arranged marriage you have a basic understanding of why you got married…it wasn’t done out of foolishness of an emotion that can die out at any given moment. Therefore you have a more realistic outlook of your marriage which makes the foundation even stronger. Carefully arranged marriages have conditions that both parties have to agree on. Nothing is necessarily hidden and everyone knows what role they play in their relationship. It’s practical and fair…atleast in my opinion.
