I would urge you to speak to settle your dispute through arbitration. If what you allege about your wife’s family is true, they are certainly aggressive and unreasonable in their demands. However, only a third party can settle the dispute amicably.
I would urge you to get everyone involved to agree to a panel and seek fair arbitration based on sound Islamic principles. Perhaps you may enlist the support of the wise and knowledgeable people in your community.
In the meantime continue to pray to Allah. Never give up offering this supplication:
Rabbanaa hab lanaa min azwaajinaa wa dhurriyyaatinaa qurrata a’yunin wa ij’alnaa li al-muttaqeena imaman
(Our Lord, grant us true joy and comfort in our spouses and children and make us role models for those who are conscious (of You.)
Almighty Allah knows best.
