How to pay back when the person you stole from refuse to take the money?

Hei. Me and my sister bought a house together. We paid 100 000 each the rest was a loan we took together. We fixed the house so we both worked there by painting and on. The same day we was finished she locked me out of the house. I couldt go in. So she went to a lawer and made papers so that i can sign the house over to her. I refused. But i wanted to get a deal so i signed the papers but i wasent gonna give them to her until we make a deal. I trusted my mother and gave my mother the papers. I told my mother not to give them to her beacuse then she will take thd house. My mother said ok but she gave them to my sister and my mother says that she stole them from her. I made her call her and demand the papers back my sister said no. She gave me my 100000 minus a loan we took to fix the kitchen. I then realized that i lost house i stole some gold from her i sold it for 23000 she lived in the house for about ten years and sold it with a profit about 2 millions. Now 14 years later i give her the money for the gold but she refuse to take it beacuse she wants to be forgiven first. I dont want to forgive her unless she gives me my half of the profit. What do i do? Can she refuse to take the money when i try to make opp for my wrong?do i have to forgive her. She wants forgivness but dont want to give anything back.what does islam say about this. I want to pay back. She lived and paid for the house i paid for rent other place so in my opinion the house was mine also the hole time cuse i never agreed to give it to her. She stole it.
