I'm upset with my wife for leaving me home alone with the kids
Was she supposed to come home earlier?
Yes. I like people who actually come home when they say they will
It's understandable to not want to be left alone with your kids. Sometimes kids can be a handful and parent's are expected to share the responsibility of taking care of them together. Explain to her that its not okay for her to leave you without a proper explanation.
Don't talk about my wife like that.
Sorry, I was trying to be empathetic. As long as you and your wife and your kids are comfortable with your situation, that's all that matters. Being honest is the best way to make sure everyone is happy.
