AITA for continuing to ban my sister-in-law (and family) from our house?

Family conflicts can become complicated when the person causing the problem is not someone you can simply walk away from. For this husband, the issue with his sister-in-law did not begin with one argument, one rude comment, or a simple personality clash. According to his wife, her sister had spent years taking advantage of other people, and over time he began seeing the same pattern himself. The situation reached a completely different level after their mother moved into assisted living and the sister was given power of attorney over her finances.

After their mother di*d, it was discovered that thousands of dollars had been spent from the account on personal and largely unnecessary expenses. Although the use of the money was reportedly legal because of the power of attorney, the husband felt the behavior crossed a moral line that he could no longer ignore. What frustrated him even more was that the rest of the family seemed unwilling to confront the issue. Eventually, he decided that while he could not control what happened outside his home, he could control who he allowed inside it.

Curious to hear the verdict from Reddit on this one.

Years later, the original financial dispute has evolved into an ongoing marriage and family dilemma. The husband has maintained that banning his sister-in-law is not about personal dislike or holding a grudge over a single incident, but about refusing to associate himself with behavior that he considers fundamentally wrong. His wife, however, is now feeling the consequences of that decision more directly, especially when holidays and family gatherings come around, and her sister cannot participate in their home. She has not been cut off from her sister entirely; the two still speak frequently, spend time together outside the house, and live only about a mile apart.

What she wants now is simply an exception for holidays so that family celebrations can feel more complete. But her husband sees that request differently. To him, making an exception would undermine the boundary he deliberately established and make his principles dependent on convenience. He understands that the situation is uncomfortable for his wife, but he believes those consequences stem from his sister-in-law’s actions rather than his response to them. Now the question is whether maintaining a permanent ban is a reasonable personal boundary or whether refusing even a temporary holiday exception has allowed an old conflict to continue damaging the family.
