Your husband is planning to buy a house by his own salary , after that also he is fulfilling your needs. now he is not looking to your parents, this question is of no use as he is allowed you to give your salary to your parents , how what things he managed just imagine?
he himself doing hard work in office means he is managing his live hood.
he managing his own family he is providing you all needs by his own.
he is looking after his mother father and brother by himself not demanding this from you.
he is managing you and your daughter of course his also but here just take it as a task.
he is managing himself also to make himself fit for doing all responsiblities....
if a perosn is doing all then definetely when any occasion comes he also manage to your family also,
after that you expecting him to look after your parents as a real son so dear madam he can become real son but does your parents become real mother & father for him..
if answer is yes-- then no need to file false 498A and DV
if answer is no- then no need to expect much more while he already doing something to your parents [ by this i want to tell just see those husband who do nothing for their in Laws ]
so you did wrong and sorry to say now after filing false case , your marriage is already come to end just wait for the day when it get finilised if there is chance you get for reunion then dont miss that chnace and do all what you can do to save your marriage and your family....
by best of luck
