I'm struggling with how to move forward with my husband’s best friend, who knew about his affair. The affair began in July 2022, and the friend found out in fall 2024. While my husband didn’t share many details and the friend didn’t press, he knew something was going on. Still, he said nothing to me and never confronted my husband. Although I know my husband is ultimately responsible for his actions, I feel betrayed by this friend who’s been like a brother to us for decades. After I found out, he was one of the first to show up to support me and our kids, and he’s continued to show concern. But I can’t shake the anger and disappointment I feel toward him for staying silent while our lives unraveled. I don’t necessarily want to cut him out, but I don’t feel comfortable around him, and I no longer trust his judgment or \influence. I’m not confident he truly has my husband’s best interests at heart—his loyalty seems unquestioning, even when my husband is clearly making terrible decisions. In many respects, they cosign each other's bad behavior and take on a "boys will be boys" mentality, which is detrimental to them both as it normalizes bad behavior that should be called out for what it is, just plain wrong. How should I approach this situation? Is it fair to expect more from a friend in this position? How do I protect my own boundaries while navigating this complex relationship?
