Arranged Marriages :
a.) Arranged marriages mostly work on obligation function.Since the event is arranged by the parents, it adds pressure on the couples and they tend to perform their duties on obligation.I have personally seen examples of couples where the husband does not feel comfortable sharing information regarding the house and does not inform the wife about the places he visits everyday or the things that happen in his office etc. The wife on the other hand,usually stays calm and quiet and remains victim at times of crisis due to lack of information. Such husbands are usually grumpy and do not like to even look at their wives and tend to have a very high preferance towards their family members and a very little or no preferance towards their wives. Another situation is where the husband performs his duties and the wife treats him recklessly.
(b)BUT, i have also witnessed couples, who behave like Best friends and share their activities, both finance and household activities.
Love marriages :
a.) Love marriages are contrary to arranged marriages where the parents get grumpy and the couple are usually happy together.The parents who lose the oppurtunity to select the bride or the groom, tend to show their grudges on the couple.In such circumstances, the couple would be depressed but they would have each other so it will be allright. They would live happily till the end of time no matter what problems they have.
b.)BUT, there are couples who tend to change after marriage .This is because, while in love there is no proper guarantee of their love story so they become 100% dedicated to each other.( This is similar to how man dedicates his life to many activities as possible because life is short and uncertain. If man was immortal, and it was certain,he would not even perform his daily duties).Once married, thay tend to lose interest in each other and divert their minds on something else.And also many couples realise they do not know much about their partner or whatever they knew about them was a lie.
Hence, there is both a Beauty and a Beast in marriages.
Therefore the success of any marriage, whether love or arranged, depends on the BEINGS (husband/wife/parents) and CIRCUMSTANCES but not the concept itself. Any marriage would be successful, if the couple live with cooperation and try to understand each other instead of complaining about everything and the parents take them with a positive approach.
