My brother has loved a girl and he is willing to marry her.
But, none of my family members are fine with it as we see a change in my brother's attitude and we are not fine with the bride's family and their values.
Before marriage itself, he has developed extensive hatred among all family members and is asking to distribute property (which we earned with efforts from all our family members) which rest of us are not fine with.
We believe in joint family and we believe in traditions and values. We feel he is forced from the bride's side that if my brother is not able to convince my family, my brother can demand for his share in our property and later they can live without anyone's help. We also feel that the bride and her parents are blackmailing my brother emotionally.
My brother started criticizing everyone in our family though we didn't utter a negative sentence about him.
We very much care about my brother and his future.
How do I convince my brother (currently he is not listening to anyone of us) and let him avoid this love marriage which is resulting in breaking the relationships in our families rather than bonding all families which generally happens in an arranged marriage.
(No engagement/discussion has happened with the bride till now).
Please help.
