What are the underlying reasons for the increasing stingy behavior among men in society today?

My husband allocates 1,000ghc daily since 2023 for our family of four. I have requested an adjustment to at least 3,000ghc, we are in 2025 but he appears uninterested in considering this proposal. I am contemplating separation. What alternative courses of action would you recommend? Our sister, Sherry Agbota needs your advice.
