Have u ever dated someone with severe princess syndrome? I dated once with such issue. Big headache. Always want me to fetch her no matter where she goes, near or far.... ON TIME. To and from work, to and from convenience store down the street, to and from one shopping mall to the shopping mall adjacent to it.

No only that, she is always right. I WhatsApp boss regarding work ugent matter during lunch hours with gf, I got nagged. I on time for cinema, she angry don't know for what reason. Eating time, need help to remove garlic and  bean sprouts from her noodles. Worse still, help her remove prawn shell. Got two time, she asked me to remove chicken and fish bone for her.

I can't stand. So, I decided to break up. She cried. Told everyone including her parents I bullied and treated her bad. I got scolded face to face by her parents who came to my office in front of my colleagues.

How about u? How u handle your princess syndrome gf/wife?

Not just her mindset need to change, TS mindset also need to change also. (Need more man) 
Your point also true also but some time need to try it first or just change the way for the conversation. Just like deep talk.
Further more relationship need to always upgrade learn each other way of thinking.
