love affair with a boy of different caste

Unfortunetly, there is no easy solution to this one. You have to understand that from your parents point of view, they want to protect you and your children from any type of harm. Even if they can understand your feelings the problem is society in general might not. What I am trying to say is that your parents probably will not accept a relationship that could lead to social exclusion (ex.:other people rejecting you, your partner and children) and social rejection (ex.: other people refusing to be your friend, give a job or help you). Going against social norms puts you and your family in a vulnerable position because of how others will react to your union. Even in western countries where caste is not an issue for mariage, people often find themselves rejected from people from their own communities because they are not upholding the common beleif and traditions inside their own culture.

This being said a few people do brave the social taboos and marry out of caste, but by doing this they are willingly accepting to cut off or highly damage most social ties with their own families and friends. This is an extremely lonely and difficult road to walk and there is not garantee for happiness in the end. You have to realise that even your children will feel the effect and rejection of a union that is not socialy accepted.

Before going further into this love affair, get informed on what your options truly are (ex.:how will you survive if you are rejected? what are the possible consequences for your children?) and think seriously about if you are truly willing to risk losing your family, friends and social network.

I am so sorry that things are can not easier for you. I truly do wish you happiness and strengh. This is truly a difficult decision.

Know that love can be shared in many different ways and sometimes really loving someone means making a decision that may lead you apart but in the end protects both of your welfare.

Good luck!
