<prompt> Human: My wife would like to control her spending better, and has more or less asked me to give her envelopes with an appropriate amount each month. Of course, this would prevent us from getting cash back on our cards paid entirely monthly, and perhaps more importantly, put a non-insignificant amount of money at risk of being lost or stolen. I brought up having her write it down, or put it in software on her phone, but that was a non-starter; we both know shed forget or skip doing it too often. An ideal solution would have a notification text app type pop up with her remaining budget every time she spends some. Meanwhile, itd allow me to remove charges from counting to the budget e.g. Emergencies. Shes already using a separate card, so I can already track her spending, I just need an automatic type solution, and havent been able to find a good one thus far. Does anyone know of a good way to do this?  <response>: If she thinks cash will work best for her, start with cash. Credit card rewards arent the important thing when youre working towards controlling your spending. As for carrying a lot of cash at once, maybe carry a weekly budget instead of monthly.
