Your a woman of course your biasedThat's fine, but you gave us an isolated incident and our evaluation of that incident is that you messed up. Past negative behavior doesn't make it okay to do this though.
I don't know if this applies to your specific case, but sometimes when people don't even want to talk about the problem it is because what you did is just plain wrong. I know I don't even bother discussing when I know that the other won't ever agree, they're definitely wrong and there's no way I'll accept it. Might be what she's doing? That you have done several things that in a common sense kind of way is just stupid, but you have, let's say a different perspective on it...
I don't think discussing anything with you is worth the time. This thread proves it, all I see is excuses. 0/10 wouldn't date you.
