Up until a few days ago, Cac was writing about HIS feelings, and venting. Though you may feel 'exposed,' and unable to defend yourself, no one knows either one of you. Most people on this board know there is a whole other side of the story that is not getting told. That is typically why this isn't just a b!tch board... if someone really gets to grinding on their spouse, most people here don't let that person get away with it.
I understand your frustration in this matter, and I know you are not feeling heard. Sarcasm can really hurt.
But guess what, honey? Now is the time for a boundary... not justifying your position. So do you want to be right, or do you want to solve the problem?
When I was married, my H was an accountant. All things related to money and investing, I pretty much left to him, since that was his area. He'd try to explain things to me... but a lot of it didn't stick in my head (though far more of it has than I ever once thought). I didn't remember things because I didn't HAVE to... not out of disresepct for him.
However, when I began my own business, we often would squabble over how I decided to do my accounting, and some business decisions I was making. So I stopped talking to him about it, and I hired my own accountant. The emmotional distance necessary to create an effective business relationship was not possible with him. I didn't do it out of spite, or because I thought his intelligence was lacking, but because it wasn't helping either one of us. Period.
You obviously have your own finances, and issues pertaining to them. Solve the problem.
Don't blame Cac for not responding to you in a way you would prefer. Set a boundary. If he wants to be blah, blah, blah, he gets to do that (good decision or bad). That doesn't mean you have to tolerate someone's disrespect. But you cannot control it.
Your emotions are your own. And while understandable (at least to me), they don't really 'help' you in solving problems. They just help you justify a position (right, wrong or indifferent).
