I talked to her briefly today - I didn't ask, but from what she mentioned about this and that it sounds like she's planning to pay off her car (which is in her name and she's making payments for out of her own money) and is going to spend some and save some of the rest. Paying off her car sounds like a good way to get rid of some debt her DH can't then just rack up again, so I'm glad she's at least thinking in that direction!
Wow! that's a better update than I expected! She really needs to keep the money she's saving out of her partner's reach, though, or those savings are just "spentings".
