Dear Rutvi,
First of all, if you ever ask any personal or similar question over internet then never disclose your real name or name of your partner.

In your case, which is not different than others, all you can do is wait. Tell your boyfriend to not force family for marriage, rather let the family know that if he is not marrying you, then will not marry anyone else either. Its simple actually, the family , specially father of the boy is kind of hurt, his ego is also threatened by past incident (marriage of his sister). So now you must make him realize that love and care for children is above everything. If he (Bharat) marries someone against his will, he will never be happy and I am sure no parents wants to see their child sad for whole life.

But you have to be patient.
