Is the institution of marriage a bit too overrated?

I had been invited to a wedding for the past three days. I am an Indian and a Sindhi so you must have imagined how it would have been. There were five functions in all- Sangeet, Mehendi, Ring Ceremony, Baarat and Reception and all of them starting 2-3 hours later than the time published on the wedding card. Apart from the groom, the bride and their families, everybody is just concerned about the food, including me. I personally prefer a Christian wedding- you know lesser functions, prettier dresses(not that ours aren't pretty) and much less wastage of time.
So, back to today's topic! I can't say I don't believe in marriages but going by the increasing rate of failed marriages, I am kinda scared of them. Whether them being love marriages or arranged marriages, you can't be sure if you are going to grow old together, holding hands, watching your grandchildren grow up and dying in each other's arms or getting into fights, get separated and hate each other for eternity. You are spending so much money on something whose fate will remain the same regardless of the cost it has put you through! Marriages being successful or not doesn't matter but showing off does.
Marriage is not the conclusion of everything. Not all lovers end up getting married and not all arranged marriages have love. It is just the way life is. Whatever is bound to happen will happen eventually and you can't do anything to change it. Getting gooey-eyed over each other just happens in the start but when the reality sets in all love is thrown out of the window. Marriage is a very big responsibility and it depends on the husband, the wife and their fate and in our cases, on both their families if the marriages last or not.
