Sounds more like "I keep giving my mom my money" instead of "my mom keeps taking my money"


You are the one with the power and the problem here, your mom's greed is just a byproduct, and her greed will grow and intensify, because you make it so easy for her to act on her greed.


Give her what you must and no more. Simple.


Repeatedly giving her money "to hold" is just asking for trouble, its like begging her to use it...


Bank or hide the rest.
