Kind of curious of how you managed to go to a casino with "slot money" when she's broke.

Have you ever considered that she may have a drinking problem? The way you wrote your post sort of infers that she spent the entire day drinking from 2am on.

I don't know, but it also sounds like you have some serious communication issues in your marriage, and if I were in your shoes I'd probably start working on that instead of running off to the casino.
