Since the two of you have married it appears both of you are legally adults in your country, with full responsibility for your own lives and the freedom of independence that comes with it.
Also, since you feel you have done everything in your power to dissuade your parents (and siblings ?) from open hostility toward the relationship, it appears you have come to the point where you must make a decision whether to leave your parents to their lives. Obviously such a decision would be emotionally difficult for everyone but you might be forced into it. If you are materially dependent on your parents the option of potentially completely separating from your parents might not be a realistic one.
Your parents obviously will be keenly interested in your future but, frankly, your marriage is (broadly speaking) no business of anybody else.
