@Chaitukpr,
With respect, Chaitukpr, she came on a forum that is international. The advice we are giving is not necessarily the advice she will take. Only she knows her situation. However, we are enlightening her as to what most of the developed world believes. The fact that Indians and many, many others world-wide, still believe in that archaic system is really too bad.
India is not the only country that needs to get its head out of the sand and realize that 'marriage' is not God-given, or even God-blessed. If it's not working, change it, whether it be a friendship, a job, or a marriage. It's only a marriage if they walk together.
When someone abuses someone else, that needs to change, as in STOP. It's bad for everyone involved and setting a bad example for the children.
The marriage, per se, isn't everything... the RELATIONSHIP is. If it's crap, it has to change.
We have the freedom on this site to offer our perspective when it is asked for. If you disagree, that's fine. But it's fine for us to disagree with you. If the advice is not what she needs, she won't take it.
But seriously, India needs to get with the program! This is 2012, not 1612!!! You all need to update your thinking just as you have your software, electronics, technology, etc.
