Hi friends, I'm Raja I'm Hindu south Indian but my girlfriend she is a Jain North Indian.. We love each other.but her parents will not allow to marry me. I can't live without her and she also same.. can you please help me how to convince her parents. Plzz help me friends..

Just explain to them that this is yourlife. You are choosing who you want to spend the rest of your life with.

Keep talking to her parents on this and try to convince.
In case they are very rigid.No point convincing them,they are not going to listen.

If you both can live without each other.forget Her..
If you cannot.. anyways you don't have any option.

If you both think that you cannot live without each other,Get settle in good job quickly in case you are not and then I think you should get married.

Don't waste your time.

If your age is below 20 the above might generally not be applicable to you.
Wait for each other for sometime..

Have your parents agreed? Ask them to talk to her parents,,

Jains are also a branch of Hinduism - so there aren't many differences... shouldn't be a major problem.

Remember, your parents look after you all your life, don't make a rushed decision and upset them, make them feel a part of the whole process and make them understand that you don't want to upset them.
