I meant "stubborn" in my sitch, because I refused to listen to people who were telling me that my wife WAS going to have an affair, because I was intentionally no longer meeting her emotional needs (because she wasn't meeting mine, or my physical needs). I just kept saying "No, she'd never do that -- she's not that kind of girl."
I was a fool, and it nearly cost me my marriage, my intact family and my future.
