Eric, I did something similar 1 week ago with my wife. We are separated and she just rents a room and is having trouble paying for that and her other expenses. I had a little extra and during a R talk we had which was actually very good I gave her some money to help make her ends meet. There were no strings attached. The effect was immediate and she remembers.
If this was/is a marital complaint about you then you have the power to either do more of the same or show her you can be responsible with money. A word of advice, if you payoff a credit card, close it, do not give yourself or her the opportunity to put this run it back up again. I would caution about paying off assets such as cars, boats, home loans etc. anything with equity attached.

Expose yourself to your deepest fear; after that, fear has no power, and the fear of freedom shrinks and vanishes. You are free.
