Yes, your parents interference will spoil your realtionship. I noticed in your post, you never wrote that you hate him or love is reduced in between...

So love is there between you.. That is the base for any relationship to float on water without sinking.. So slowly make him understand your feelings...Fighting with him will take you nowhere. Talking can solve the problem. Make him understand that you are responsible.. Never say again that he is earning less and you are earning double.. Money will surely create problems...Leave money aside and show your love  and care to him and talk with love to him. This way you can make him understand and give a chance for him tio rectify his mistakes. Afterall he is saving the money for your future and kids only know

 What's your problem Dear! Such hubbies are not born everyday. He is ready to take care of your every problem,howsoever mundane.It should be fine with you.Enjoy worry free life.Study further,concentrate on your career,prepare for the civil services,Just make most of your blessed condition.As far he is concerned ,it's nothing but manifestation of his inferiority complex. Also ,encourage him to progress in his career too lest he ends up playing a second fiddle to you.Between the two of you conquer the world.
