Marriage registration

Myself madhuri from Calicut,Kerala.Am 22years old and a Mtech student at Chennai.Last year i got married and it was purely a love marriage.We were in relation from past five years and even our family know about this affair.My parents are strongly against this relation and they tried to brainwash me in many ways.They are against us only because of a single reason that is,we both belong to different casts.We had no options other than registering marriage .Our marriage held at aryasamaj mandir on 11th october 2015 without my parents knowledge.Due to some personal problems and family debts am not in a situation to stay in his place at present.After marriage we are continueing as normal couples and we stay in our own houses,as only some of our friends know about the marriage.Till this date my parents are not aware of this marriage.My husband is working abroad and he is very supportive.I hope my parents might support us and our problems will be solved within an year or two.But at present we are in trouble that in coming two years if my parents come to know that we both got registered our life wont come to a gud end.We are sure that it won't reach them through our friends or others.I would like to know other possibilities if any.Also our registration was done from a municipality in the neighbouring district.Please do help me...
