I understand the reciprocation part of you paying more now that you have a job and she supported you earlier.
Why does she feel she is running low on money if you are paying more of the bills? has her income decreased or is she just spending more impulsively now that she is a WAW. Is there an agreement on which bills you pay vs which the W pays each month?
If there is an agreement, which can always be changed, and she knows what she is responsible for each month how can she be forgetting about bills? Is it a purposeful lapse to get you to pay even more?
I agree with letting your W fix it herself. Just make sure that your credit rating doesn't suffer while she fixes it.
I don't mean to sound negative just wondering if you are being taken advantage of.
