My husband, “Mark,” and I are in our late 50s and recently married. We knew each other for decades but began dating after I moved back to the area during COVID. His family is close, and his mother expects everyone to attend family gatherings. The family includes my FIL, MIL, SIL, BIL, Mark, me, and Mark’s two adult sons.
SIL has a history of criticizing Mark, holding grudges, and being insulting. For example, at my stepson’s birthday, she gave him a gift card saying, “I will take you and buy you some shoes that aren't from Walmart, unlike your dad.” This was early in our relationship, and I had no idea she was like that. Her parents made her apologize to Mark the next day.
To complicate matters, I have life-threatening allergies to several things, including peppers, fragrances, and flowers. SIL dismisses them as drama and makes little effort to accommodate me. As a result, I’ve had multiple reactions at her home.
About four years ago, SIL and BIL hosted a Father’s Day gathering. SIL insisted on making kebabs with peppers because she thought her dad liked them, despite my severe allergy. We asked her to prepare separate pepper-free food and keep it separate for me. She agreed.
When we arrived, the peppers she cooked made it difficult for me to breathe inside her house. SIL assured us the food was safe, but I struggled despite my usual allergy medication. I learned from my MIL that the chicken was marinated. I asked for the ingredients, but SIL dismissed my questions and said I didn’t need to worry about it. I had to insist 3 times before she gave me the ingredients.
I went outside considering calling 911. When my MIL came to check on me, I told her, “My SIL keeps trying to kill me off.” I meant I felt unsafe, not that SIL had deliberately poisoned me. I was sick for days and missed work. SIL blamed me for not providing enough information and never apologized.
Afterward, Mark and I began hosting family gatherings for safety reasons. Everyone, including SIL and BIL, attended without incident.
Months later, while we were planning my birthday, my FIL called Mark, furious with me. SIL claimed I was still talking about her, had told someone outside the family about the incident, and had posted about it online, damaging her reputation.
I never posted anything about her. We did tell friends what happened at the time because I was explaining my illness. There was nothing to apologize for. Mark defended me, but my birthday was ruined. SIL and BIL now refuse to attend family events if I’ll be there, and his parents expect Mark to fix things.
I suspect one of Mark’s close friends may be stirring things up with SIL, but I can’t prove it.
AITA for refusing to apologize when I never posted about her or tried to damage her reputation?
