This is really tangled. His sister-in-law took your money with ulterior motives, which is against the law. It should originate from his parents and be regulated by them. After all, you are not married. But your life has nothing to do with his sister-in-law. You are engaged, which proves that you love each other. As for poverty? It depends on your boyfriend's efforts to change the status quo. A family has two sons. For farmers, the financial conditions are really tight, and there are disputes. Parents have the right to distribute their property ownership, which cannot be a stumbling block to your marriage. As long as you are absolutely loyal to love, I wish you happiness.
