You have a big question that needs many answers.
Alot of your answers will not be given to you 100% from here because there are very few people from India here.
In america, we dont have to have arranged marriages.
Getting a divorce is not a shame to do, and we dont have to pay to have another arrangement made.
So I dont know what that truly feels like.
Having said that, I truly believe if you are that uncomfortable and that unhappy with your marriage, you should find a way to divorce.
It is not fair to you .
And what if he starts cheating? He could bring you a disease. Then you would be the one sick because he isnt happy.
Im sorry that he seems to ( from what you are saying) completely judge you by looks alone. That has to feel terrible.
But, he is not the end all, say all of everything. He is not the last person you will ever meet.
And I am sure you know someone who has had a divorce? And remarried?
They are probably happier this time around huh?
It might be hard to deal with your societies hard rules about a divorce, but it would be easier to deal with that then be in a relationship where you are made to feel bad because you are not what someone else "wants".
I am sorry you got dealt that crappy hand.
No. Most marriages are NOT like that at all. I think there is a real sign, from what i can tell with this post alone, that there is something wrong.
There is no shame in making yourself happy by getting a divorce.
If you feel that is a good answer, then do it.
