It makes me feel good!

My husband is hot tempered, mean spirited and just plain rude the majority of the time. We make decent money together but after the bills are paid and savings put away- I spend whatever is left...to the penny. I struggle with my shopping habits but it seems like the only time I feel good about myself is in the dressing room trying on new clothes, shoes, purses....you name it. I usually feel guilty about the purchase afterwards and half the time I never even wear the stuff, it's just like a high when I am purchasing them. I wish I could just get the love I needed from my husband and keep the money in the bank.

Major passive aggressive anger issues. He makes you feel ticked. You can't conceive of how to address it with him. You think "I'll show him." You blow the money. "That'll teach him to mess with me."
You won't get the money under control until you find a cleaner way to address your anger with your husband. Also, you need self affirmation in ways that does not consist of collecting things.

I agree with Elise!

Your pursuit of happiness via materialism is only an excuse not to deal with your own problems. Things cannot be transplanted in the place of a peaceful and content heart. My advice would be to deal with your own feelings of sadness and know exactly why you feel the way you do about your marraige. THEN search out a way to calmly communicate one on one with your husband regarding the obligations and responsibilities toward each other.

Sounds like you need to find something to occupy that active mind of yours. How about exercize, volunteering, taking a cooking class, Meals on Wheels. Anything that keeps you constructively occupied.

Well just follow what you think leads to happiness for yourself. cos different things make different people happy. we are all individuals.
