Decide to get used to it, or keep telling her it's not right, and she does it again and again. Or date another woman and experience the same behavior, then stop, and date another again. Repeat that circle. These are some options.
In developing countries, people live in communities, they borrow from each other, they involve in each other's lives tightly, they meddle, they privy through their neighbor's stuff, and they easily strike conversation with a total stranger to seek favors. These behaviors are normal in those poor countries. In fact the behaviors are valued because they help the people to survive.
But the behaviors are a turn-off for people from developed countries where privacy is valued the most.
All sorts of theories try to explain this nosey or intruding behavior. I believe most people in developing countries behave like that. Perhaps it's because of the poverty which makes people there to value community living over individuality seen and valued in America, western Europe, Canada, and other developed countries.
