People Request For Us To Assess Their Intriguing "Am I The Jerk?" Stories

"My mum has an odd relationship with my fiancée, 'Anna.' At first, my mum strongly disliked Anna for no particular reason. She would always make comments surrounding Anna’s appearance, her job, her family, etc. It got to the point where I had to cut all contact with my mum because her comments were putting a serious strain on our relationship. Over the past two years, I don’t know what flip switched on inside my mum - but holy cow - all of a sudden she adores Anna. It took Anna and me a bit more time to accept my mum’s sudden change in behavior, but it’s been smooth sailing ever since. She won’t stop gushing about Anna, and she wants to be involved in Anna's life. Anna enjoys her company despite their 'rough start.' Anna and my mum used to see each other almost every week or every other week. The global crisis is largely at fault for putting a stop to their weekly visits, but they’ve still largely kept in touch. I think my mum really misses Anna and wants to spend time with her at every opportunity she has. Though Anna likes my mum, I don’t think she’s up for seeing my mum as often as she used to, (I don’t think this is anyone’s fault per se, my mum is a very loud and outgoing person and Anna just needs time to destress + she works a very demanding jobs and would like her weekends to herself. We’ve communicated this to my mum.) Anna’s brother passed away almost a week ago. He was in hospital for a few months, but his health was progressively getting better and everyone, especially Anna, thought that he was going to be out of hospital soon, but he just unexpectedly passed. Obviously, Anna is devastated, she hasn’t been sleeping well, or eating well - and on top of all her stress, she has to take care of her brother’s young kids. She’s exhausted and doesn’t have much time to herself. My mum, without any warning, came by my house in the afternoon demanding to spend time with Anna. Anna was taking a nap at the time, so I asked my mum to be a little quieter and assured her that Anna would wake up soon and talk to her. My mum wasn’t satisfied with that answer and started making a lot of noise to try and wake her up. I tried to explain to her that Anna has been extremely busy and she’s been dealing with the death of her brother etc. My mum refused to hear it and responded with, verbatim, 'Well it’s not as if his death was 'unexpected'.' And many other people have a lot more on their plate so I don’t know why Anna can’t just 'suck it up.'' I, at this point, was furious with her - so I basically threw her out and called her a 'heartless witch who has no real sense of empathy.' This single comment caused my mum to get angrier with Anna and a few more family members to send her a few nasty messages. I don’t want Anna to bear the brunt of my mistakes, and I’m wondering if that comment maybe went too far."
