NTA. Why do certain parents act this way? My wife and I chose not to have to children and we’ve run into this before. I VERY bluntly let people know that it is their kid. Not mine. You chose to have it. I will not be responsible for it. Period. My sister pulled this on us and I told her under no circumstances do I want to deal with my nephew on my own. He’s a great kid, but no thank you.
