Even if that nonsense were true, how does it follow that YOU are responsible for HIM being stress-free? You're right. They have hands.

By the way, overspending is possibly a sign of bipolar. Is that one of your diagnoses? Did you mention it to your p-doc?

As far as practical advice (and I agree with you, let's see if the meds make any difference) what about writing down everything you spend money on? This will help you see where it's going and what you're most likely to spend on. Figure out what need it's meeting, and if you can meet that need some other way. (Hint: Losing weight ain't gonna make a dang bit of difference.)
