One year in but a newbie

[Lifes Twists]

This week has been a crazy week and I need some advice on how I should proceed. To start off last Sunday my wife went out on a first date with someone. I found out from my daughters, but did not ask too much. On Monday i went to doctor and got an antibiotic for a head cold. Tuesday morning before work I found my basement flooded due to a broken water heater. Thursday I got a letter from the finance company that my wife has fallen behind on her car payment. Last night my wife called asking for help. She has screwed up her check book, has no money, maxed out both her credit cards and been rejected to cosign a college loan for my oldest daughter. She did offer to come to the house and help me clean up the mess that the flood has left.

Do I step in and offer to help her get her finances under control?

Do I let her come over and help me clean u the mess left by the flood?

The agreement was that she would cosign oldest daughters college loan and I was going to cosign middle daughters loan. Do I sign both now and hope they accept me for both or push back and see if she can get one of her family to cosign?

I don't want to let her cake eat. I also don't want her to feel I am persueing her. I also don't want to rub her face in it. How do I proceed?
