How many of you have signifigant others that constantly overspend and screw up the checking account? I had a separate account for a year with no probs, my wife gets on it and she's already screwed up in less than a month.

She bounces checks like crazy and has been banned fron two banks in town because of her irresponsibility. She said I was treating her like a child not allowing her on the account yada, yada,yada and here we go again.
Is it bad to want to bitch slap your wife? (have never hit her by the way)
but I would like to right now!
