AITA for telling my sister that I am not bringing her kids if she doesn't stop criticizing my husband.

I have a sister, Mary, who isandeliered as my mother's helper. I wasn't the oldest but I was the one who helped the most. I have 2 other sisters. We all live far away except for Mary who lives with our mom. We all come once or twice a year to visit.<br><br>I usually bring my kids with me, but this year I came alone. I had a babysitter and I didn't want to disrupt my kids' lives. My sister was a shock when she saw that I came alone. She asked why I didn't bring them. I told her I didn't have to. Then she said that mom missed her grandkids. I told her that mom saw them last year and could wait to see them this year.<br><br>Mary kept pushing that I should have brought them. I finally lost it and told her that I didn't bring them because the last time I did she kept criticizing my husband. She said he was a jerk to her kids. To be clear my husband is not a jerk. He is shy and can't make friends easily. My nephews and nieces are noisy and he doesn't know how to handle them. He is a quiet man who likes to read a lot. My sister said that he was rude to her kids because he kept telling them to be quiet. He apologized to her kids but my sister was still mad at him.<br><br>I told her that I was not going to risk my kids being called uncle's fans because he likes to read. I told her that if she promised me she wouldn't call him a jerk or make him feel bad then I would bring my kids. She called me an asshole and told me I am making a big deal out of this.<br><br>Edit: I forgot to mention that my sister's kids call my husband library man because he asked them to keep it down while he was reading.
