Muddle,
I too am a plactor. I apologize for things that maybe I shouldn't. I don't like to rock the boat. That being said though, my perspective on what you just wrote is this:
1. You kind of sound like you are being vindictive and nasty by telling her it's none of her business what you do. It is her business, you two are still married.
2. She has told you several times that you don't make her feel happy. Maybe you need to work on that more even if you get anger and nastiness in return.

Just my 2 cents; take it with a grain of salt.
