Has your saving habit changed suddenly, or has it grown gradually over time? if the first, then make sense why she's making a fuss

are you able to earn more? if not, are you willing to meet her in the middle? spend slightly more, e.g. last time save 6k, now save 4k, or 3k since you have 100k edi, not to say that's much but changing your wife is harder, maybe can but it takes very long time, so mean time maybe u can try what I mentioned
