Unfortunately, my situation is not a hypothetical.
Years ago, I was not 100% supportive of my wife when she had disagreements with my sister or mother, each of whom lived within one mile of us. My wife always prided herself on being independent and being able to stand up for herself. Self made woman, college educated, MBA, started her own business, etc. As I think back, I was probably 40% to 60% supportive on average. I didn’t realize that it was important for her to “win” those arguments.
So when I agreed with her viewpoint, I supported and defended her. When I didn’t, agree with her, I did not think that she “needed” me to defend her. In fact she would kind of talk over me as if I was getting in the way of her argument. When she would capitulate, then afterwards she would start to resent me. “Why do you agree with _______?” And I would explain why, but what she was really saying was “I need you to support me.” But I didn’t get that message (typical male). I am just like my father: the peacemaker. Go along to get along. Pick your battles and win them when it’s important, etc.
So that total disconnect was a major contributor to ruining our relationship. After my father died, I then got more drawn in to these “tiffs” and stumbled into that peacemaker role. I had experienced my grandparents getting into arguments with their siblings and not talk to them for years. My father eventually played peacemaker, and this was for his in-laws. Eventually, there was a peaceful resolution. Not long afterward, my great aunt died, and my grandmother (her sister) was devastated that she “wasted” ten years of their lives fighting (not talking), then they reconciled, then her sister died. Regret. My grandmother was miserable for the rest of her days.
So as the peacemaker, it worsened my wife’s experience dealing with her in laws. As peacemaker, I became her enemy, cause I would not support her unconditionally. Combine that with too much time and effort trying to sustain a family business enterprise, and something had to give. One day she told me “I have replaced you” and she was dead serious. That was over thirteen years ago and she hasn’t spoken to me since about anything but bills and other problems, and (sometimes) our kids. We live (bad choice of words), more like exist, as two separate people in our house (not much of a home), living separate lives. She has also drifted away from the church, while I have come to embrace it and rely upon it more than ever. I pray that we will somehow reconcile, with God’s help.
So, I would agree that husbands especially should always support their wives without any preconditions. Also, don’t ever assume anything about your wife’s relationship with your family or friends. Ask questions and discuss these things, even if it isn’t in your nature to do so. Your relationship depends on that.
