I have a very toxic and narcissistic sister-in-law. Despite years of unpleasant family problems caused by her, my husband and his brother (her siblings) feel obligated to stay in contact with her. Now that their parents have passed away,

Dear Conflicted: Your daughter’s wedding is her day, and her wishes should be the priority. Explain to your husband that the decision to exclude his sister is about ensuring a positive, stress-free event for your daughter, not about hurting anyone.

However, I know this will cause conflict with my husband, who may insist on including them out of family obligation.

"How can I handle this situation while respecting my daughter’s wishes and avoiding unnecessary family drama?"
