My Husband Won't Speak to His Brother. Should I Stay Out of It?

The Letter
My husband and his brother had a painful falling out two years ago, and they haven't spoken since. My husband refuses to discuss what happened and becomes defensive whenever I suggest reaching out.
I know it is ultimately his relationship and his decision, but the estrangement affects our entire family. Holidays feel tense, our children rarely see their cousins, and I worry that the distance will become permanent. Part of me believes my husband may regret losing these years, but I also don't want to pressure him or dismiss whatever pain led him to step away.
Should I bring it up again, or accept that this is his choice and stay out of it?
My Response
It may seem that you have two choices: either decide not to interfere and make peace with your husband's decision, or say what is honest for you and accept the discomfort that may follow. Neither choice is a walk in the park.
Instead of focusing on the outcome, it may be more useful to ask which response is most aligned with your values. Whether your husband speaks to his brother is outside your control. What is within your control is how you choose to respond to the situation.
It is easy to fall into the trap of staying quiet and becoming resentful (being too accommodating). It is also easy to speak up and then become angry when your husband does not respond in the way you hoped. For both reactions, I wonder if there is a desire to control an outcome that is not yours to control.
You can be truthful about how the estrangement affects you, the children, and the wider family without trying to force your husband to reconcile.
You might tell him what you feel, what you are worried about, and what you hope for while still acknowledging that the final decision belongs to him.
In my experience, letting go of the outcome may make it easier for your husband to hear you, although there is no guarantee. Your task is not to make the brothers reconcile; that's their work. You are responsible for your feelings and perspective while respecting that your husband has his own decisions and preferences, even when they differ from yours. If you can accommodate his decision and let go, that choice might work for you. If you can voice your perspective while also understanding that, ultimately, he gets to do what he wants, then that might also be a choice. Choose whatever is workable for you.
