Dear Suraj Singh,
I completely agree with Mr T Kalaiselvam. Do not rush into anything which you will regret later. If you really want a divorce its fine - but do not rush into it. I am sure that before getting married you would have really thought about why you want to be married to so and so person - and I hope that you spent sometime coming to this decision, - so now do not make a contrary decision within just 3 months.
I know that sometimes we all feel that 3 months is long enough time to understand a person - but let me assure most of the times even an entire lifetime is not enough to understand another person. I had read somewhere that if you stay with same person for long enough time you like him/her irrespective whatever characteristics they possess as "EVERYONE" in the world has at least few things that are unique and endearing about themselves.
These issues of getting angry, going away from home to parents house etc... are all very common not only now but even in older times. But in older time due to many social and economic reasons things would never become public knowledge or go upto legal level.
So please give yourselves time and patience before you take any legal approach - this is my sincere advice. Going legal way would most of the times make things worse and not better for everyone. So try all other approaches first.
I am not a lawyer but have seen my fair share of lawyers while i went through similar situation in my life. Please remember that lawyers are much like doctors - most of them will be very technical in nature and advice you from that perspective - which is really good and useful by the way. So getting a divorce while not being "Very easy" - I am sure it wont be difficult. The difficult part is to see if you can work this out without going that road. So try doing the difficult part of working this out first - if it does not work legal path anyways will always be there.
My sincere advice - please give time, let things settle down, (as Mr Kalaiselvam says in his post - Try reconciliation - if it does not work, give it another 6 months without contact her) by then I am 100% sure you will know what to do and how to do this - whether divorce or rework the same.
ALL THE BEST :).
Johny
