Love the savings idea Lambkins. Of course I have no change, the little people use it for lunch money.
I think the boyfriend monitoring the money is a horrible idea happybanana because that will just lead to some huge fights. I have two girlfriends who are complusive shoppers, one started exercising (she couldn't shop until she did her hour of exercises each day), the shopping has cut way back and she looks great. I think hers was triggered by a mild depression and boredom. My other girlfriend has declared bankruptcy and is still spending. She cannot see she has an issue at all. She has tons of jewerly and keeps buying more. She has tons of clothes in all sizes but keeps picking up new things. I've tried to talk to her about not shopping so much but it turned out to be an awful scene.
It's a hard thing to stop doing, but you need to figure out a way to do it that works for you. I think realising it is the first step.
