You being the son boldly accept that your mother, sister and your aunty have been meddling with your family life and want to separate you from your wife, this being so, you have moved out of the house and have been staying independently since march. that is really bold.
if you wish that your mother, sister and aunty do not meddle with your life's you must lodge police complaint's against them, if the cops fail to take the complaint, file the complaint directly with the magistrate U/s 200 of Criminal Procedure Code.
Also in addition you can file a civil suit against these persons and take an injunction order against them from meddling with your life in future. this can be filed by your wife or you can do it also.
If your brother was made to go through the same torture, include him as one of the complainants and file it jointly, it will be stronger as well.
