I have only met my future sister in law in-laws once at her wedding. My parents were not invited to my future sister in laws wedding because my fiancé and I were not engaged yet and his parents forbid it...(i was almost not able to attend because we were not engaged Indian culture) anyways, my fiancé parents said we have to invite his sister's in laws to the wedding and his sister too is saying we should, it would be a nice gesture.
My fiancé has met his brother in laws parents twice only, there is no relationship.
My fiancé's parents are now saying they will pay for them to go. My parents have said they do not feel that they should be invited since my own sister is not inviting her in laws. This is becoming a mess, what should i do?
