The poster describes the tense relationship with their ex-mother-in-law (ex-MIL), who has long suspected that the poster is misusing child support money for personal indulgences. The conflict escalated after the poster wore a sweater to a family gathering, which ex-MIL immediately criticized, accusing them of spending her son’s money on luxuries instead of using it for their child. In response, ex-MIL demanded receipts to prove that the child support money was being spent appropriately. The poster seems prepared to provide those receipts, hinting that the situation could get more complicated from here.
