From what I have seen it is not at all unusual for people in your H's situation to choose someone the exact opposite with whom to have an affair. It seems to me that's exactly what he has done with this controlling dominatrix.

It won't last and if you keep up with your 180's and make yourself someone who is capable of being an equal partner in the future, I think you'll turn his head.

Don't be surprised though if, as your independence grows, you occasionally ask yourself why you'd still want to be his partner smile. I think he's going to have some work to do to win you back before it's all over.
