TTL, I don't have any words of wisdom.
Money issues trigger me something wicked -- we lived in a super nice house in a fancy neighborhood; AXH was drinking top-shelf alcohol and yelling at me for spending too much money on food. It's something that's following me still, four years after the divorce. Always worrying about whether there's going to be food.
The general thing I would say is don't focus on this -- focus on whether you want to continue living like this. ((hugs))
