Ooooh Spangly,
Complex issues here. The transferring the focus, dare I say addiction, from food to buying clothes etc, is something many of us can relate to. I KNOW i can.
It's more complicated because you've got lots of other issues here - the financial previous history, the sort of balance of power in your household over the finances, your need to feel in control of what you earn, enjoying looking and feeling good, possibly your husband's insecurity around that, how he feels about not working.
Have you got a good LLC or group?
If it was me I would write down the issues, separate them out, definitely try and discuss with OH, but out of the house if possible.Try and find out what he's really feeling too.
Good luck hun, not an easy one. Let us know how you get on.
Good luck xxx
