Is this too much to ask for?

I’m really troubled by the fact that my mom raises the issue of “being rude” to my aunt when she visited us.

To give some context, I have shared in this platform about how my aunt and cousin was invading my private space when they came over to visit last year during Christmas holidays. I couldn’t afford to negotiate that despite the fact that I was sharing my grandma’s bedroom. This was especially since, I had a few coursework submissions due that academic year.

Fast forward 5 months after that incident, my mom is still guilt tripping me about how I disrespected my aunt when they came over. My mom herself has confided in me occasions when she felt uncomfortable by how intrusive my aunt was, but surprisingly she doesn’t understand my discomfort. I honestly have lost confidence that my family will help in this process, but I simply cannot allow it to happen anymore.

Which makes me wonder, is there a correct way to assert one’s boundaries? I would call my behaviour, agitated and firm, but certainly not aggressive.

Fun fact, my aunt usually expects my family to understand her plight when we stay at her place. It’s just funny how she doesn’t understand mine.
