Lou..I was thinking is money and her spending are issues with your marriage........why not seperate your finances totally. Whats yours is yours and hers is hers. If she spends all hers then she will have nothing. But let her know that you will not contribute any money to her if her money is gone.
I know if I worked hard all my life and had money coming in I would be resentful if someone tried to tell me what I could and couldn't buy. But then again it sounds like she is way out of control.
Have you always catered to her? I mean if she doesn't like your way of vactioning why not just have gone all these years and did what you wanted to do. You are married yes but not enititled to have to live a life like hers.
