I only skimmed the replies, so forgive me if I repeat what someone else already said.
OP, I think you are confusing “apologizing” with “admitting I’m wrong.” There is a difference between the two. You can be right and still be hurtful, disrespectful, arrogant, etc. You can “be right at the top of your voice.” You can
unintentionally hurt the one you love. You might be right in the sense that you can prove it scientifically, and still be wrong in the way you come across. Yet, even if you’re “right,” these things still call for an
apology.
Sometimes, she’s not going to care how much you know, until she knows how much you care. Sometimes you will think that she is saying “you are wrong,” when what she’s really saying is that she wants you to support her, to be there for her, to be on her side, to listen, to really hear her, and–probably most of all–to CARE what she thinks, even if you don’t necessarily agree.
In marriage, a difficult thing to remember sometimes is that a disagreement with your spouse is not about “winning the argument” because *the goal is not to defeat your spouse–*it’s to come up with a solution that you can both live with. And it really doesn’t matter how “right” you are; if you always have to “win,” no matter the cost to your marriage and spouse, then
you are still wrong because your pride is a priority over your spouse. I’m not saying that you, OP, are doing that; it’s just a point for any spouse to keep in mind when we’re fighting that temptation to “prove I’m right” at those times when it’s really more important to let a spouse feel heard and respected.
In marriage, you are on the same team, and you both have to learn to respect each other’s opinions and feelings, even when they make no sense to you. Just because we both speak American English doesn’t mean my husband and I always mean the same things with the same words.

For instance, when you say you think she’s “unreasonably upset,” to me, that implies both that you think she’s being unreasonable, and that you know better than she does how she “should” feel. That’s probably not what you meant, but that’s what I would hear, and what she may be likely to hear.
So then you end up fighting, not because your spouse disagrees with what you said, but rather, with how you said it… (yeah, BTDT… last night, in fact…)
