Elder Care Anger and Resentment - Does Anyone Else Feel Taken?

Does anyone else feel taken advantage? It's as though my mother expects me to foot the bill for everything. I am fed up. She has an income, a decent income. She ignores it when the check comes to a table, checking out at stores - unless she's shopping for more stupid clothes.

Dinner, she orders the most expensive item on the menu and expects whomever she's out with to pay. If you announce loudly - so she can't pretend not to hear that it's dutch treat, ooh, she's offended. I had chores around the house and always did. I started those at a young age, too.

- No, I did not grow up privileged.

- No, I was not given cars, fancy things, or college - I worked and earned or got scholarships and still worked.

- No, my spouse does not support me. I work. I always have worked for 30 continuous yrs.

I am fed up. Where does this attitude of entitlement come from?
