1. This is a common problem,
2. Your mother in law also will lodge a number of complaints against you,
3. It more a domestic problem than a legal proble,
4. I do not think that you will agree for a divorce with your husband on account of your mother in law,
5. It may also a fact that your husband will not agree to leave his ailing mother and seperate from her,
6. If your husband agrees, leave the house and take up a seperate rented house,
7. If he does not agree, adjust with your said problem in everybodys' interest.
